It points towards Mecca!
Islamic and jihadist design elements in the proposed Flight 93 memorial
(Four page flyer handed out at Somerset Flight 93 meeting, 2/18/06, here with enlarged graphics)

Three key facts:
These facts are detailed in the following five exhibits (background information at Error Theory blog):
Exhibit I: The Mecca orientation of the giant crescent in both the original Crescent of Embrace design and the redesign.

The longer red line in the image on the left crosses the
most obtruding crescent tips of the original Crescent of Embrace. The
perpendicular bisector depicts the orientation of the crescent. It points 53.46
degrees clockwise from north, which is 1.73 degrees steeper than the true Mecca
line (55.19 degrees from North). See exhibit IV for simple instructions on how
to verify these calculations for yourself. Graphics are from the
site-plans available on the Memorial Project website.
The upper crescent tip is the end of the thousand-foot-long, forty-foot-tall,
Entry Portal wall. This wall, and hence the upper tip of the crescent, remains
unchanged in the redesign (image on right). A few trees were added out beyond
the end of this wall, but since the upper crescent tip was not defined by trees,
adding a few trees in this area does nothing to affect the crescent tip, or the
orientation of the crescent that it defines. The bisector still points 1.73
degrees from Mecca.
Here is an illustration from the redesign, showing how overtly the upper crescent tip remains in place and unchanged:

The end of the giant wall was the crescent tip in the original design. Unchanged in the redesign.
The
first time Murdoch tried to sneak a half-mile wide Mecca-oriented crescent onto
the crash site, he was caught by gate security (the American people). The
Memorial Project told him to go back outside and try again, which is exactly
what he did. The only change Murdoch made was to put a fake beard on (the couple
of extra trees to the left). The crescent tips, and hence the presence and the
orientation of Murdoch's giant crescent, remain unchanged.
A crescent that people face into to face Mecca is called a “mihrab” and is the
central feature around which every Mosque is built. Murdoch’s design also
contains other typical mosque features, such as the 100 foot tall Tower of
Voices minaret, formed in the shape of an extruded crescent. Another typical
mosque feature is a pulpit, or mimbar. You can see a possible epic mimbar in the
graphic above.
In all there are a dozen typical mosque features, all of which can be seen to be
realized in Murdoch’s design on the same epic scale as his giant mihrab. But set
that aside. All that we are trying to get people to understand now is the
Mecca-orientation of Murdoch’s crescent. Once this is understood, most will
agree that planting the central feature of a mosque on the crash site is in
itself unacceptable.
Exhibit II: The crescents of
trees surrounding the Tower of Voices replicate the Mecca-orientation of the
giant central crescent exactly.

A line across the most obtruding crescent tips of the Tower array (red) has
virtually the exact same inexact-Mecca-orientation as the bisector of the line
across the most obtruding crescent tips of the giant crescent in Exhibit 1 (1.79
degrees steeper than the true Mecca line, compared to 1.73 degrees steeper for
the bisectors of the giant central crescent). This redundancy confirms that the
almost-exact Mecca-orientation of Murdoch's crescents is no accident.
Exhibit III: Not just a mosque, but a terrorist memorial mosque.

When the original Crescent of Embrace design was unveiled in September, onlookers were aghast to see planted on the crash site, not just a giant Islamic crescent, but a full naked Islamic crescent and star flag:
Looking closely at the copse of trees, one discovers that it is centered slightly to the side of the bisector of the giant crescent, placing it not quite exactly in the position of the star on an Islamic flag. If one looks inside the copse of trees, however, one discovers what IS centered on the bisector of the giant crescent: a separate upper section of the memorial wall, the lower section of which contains forty glass blocks, inscribed with the names of our murdered heroes. Here is a detail from Exhibit I:

Bisector of giant crescent passes through the center of a separate upper section
of memorial wall (demarked by the path that passes through the wall from the
left).
This upper section of memorial wall is the true focus of the memorial. Placed as
the star to the crescent, it is integrated into the Islamic symbolism of the
design, while the section of memorial wall dedicated to the murdered passengers
and crew is literally off to the side. The upper section of memorial wall also
contains glass blocks, three of them, inscribed with the date: September 11th,
2001. The date goes to the star on the Islamic flag. The date goes to the
terrorists.
There is one last glass block on the flight path: the large glass block that
dedicates the entire site, placed at the end of the Entry Portal Walkway. That
brings the total number of glass blocks on the flight path to 44, exceeding the
number of our murdered heroes by the number of their murderers. Could the 44
blocks be a coincidence?
Swing the crescent tip line in until its bisector points exactly to Mecca and see where it lands:

Exact Mecca tip-line passes through the 44th glass block, at the end of the Entry Portal Walkway. Bisector points 3/100ths of a degree off the true Mecca line (which is exact, within the pixel resolution of the graphics).
Notice also that if this line is projected upwards, it lands on the termination
of a second, outer, and more recessed, Entry Portal wall. The most obtruding
crescent tip, defined by the end of the inner wall, orients the crescent
slightly off Mecca. The end of the outer wall offers a similar but hidden way of
defining the crescent, this time oriented exactly on Mecca, and the key to
discovering this hidden exact-Mecca-orientation is the 44th glass block.
Could this possibly be a one in a million-trillion lightning strike of
coincidence? See Exhibit IV.
Exhibit IV Exact Mecca orientation repeated in
the Tower crescents.
To go from the inexact-Mecca-orientation of the central crescent to the
exact-Mecca-orientation of the central crescent, just swing the crescent
tip-line in from the most obtruding crescent point on top to the more recessed
crescent tip that sits slightly further out (as described in Exhibit III above).
This structure is repeated in the crescents of trees that surround the Tower of
Voices minaret:
Swing the red line that crosses the most obtruding crescent tips inwards until it kisses the next most obtruding crescent tip on the bottom (black line) and you get the exact direction to Mecca, within the pixel resolution of the graphics. (The black line points 55.13 degrees clockwise from north, 6/100ths of a degree steeper than the true Mecca direction.)
To
see directly how the same pattern of inner and outer crescent tips yields both
the exact and inexact Mecca orientations of both the red maple crescent and the
Tower crescents, just rotate the red maple crescent graphic 90°
counterclockwise:

The red maple crescent, with exact and inexact Mecca tip-lines, rotated 90° for easy comparison with the preceding Tower-crescents graphic.
The red lines in both graphics are about 1.75 degrees steeper than the true Mecca-line (1.79° and 1.73° in the Tower and central graphics respectively). Both black lines point exactly at Mecca, within the pixel resolution of the graphics.
Both inexact Mecca-orientations connect the two most obtruding crescent tips.
Both exact Mecca-orientations swing in to the further out and more recessed
lower left crescent tip.
Exhibit V How to easily
verify for yourself the Mecca orientations of Murdoch’s crescents.
Great
circle calculations: A variety of great-circle
calculators are available online. I used the one hosted by the Kansas City
Amateur Television Group (http://www.kcatv.org/).

Google Earth gives the coordinates of the crash site as 40:03:07N by 78:54:17W and the coordinates of Mecca as 21:25:48N by 39:49:12E. Punching these numbers into the KCATV calculator, the direction to Mecca comes up as 55.19 degrees.
Screen-shot of calculator at left. Different calculators use different
assumptions about the shape of the Earth, but they all yield directions to Mecca
from the crash site that are within a tenth of a degree of 55.2.
Screen-shots of graphics:
To take a screenshot of a graphic on a Windows PC, press “alt” + “print screen”
at the same time. The screen-shot is now on your clip-board and can be pasted
into a graphics program.
Arctangent calculations: For those who graphics
programs do not calculate polar coordinates, the arctangent function provides a
simple way to convert rise and run in pixels into slope in degrees. (Plain-Jane
Microsoft Paint has pixel counters at the lower right of the screen.)

For any right triangle, the tangent function of an acute angle A is defined as
the ratio of the side opposite A to the side adjacent to A. Tangent (A) =
(a/b).
The
arctangent function is the inverse of the tangent function, thus A =
arctangent(tangent(A)) = arctangent(a/b).
Example: In the first image of Exhibit I, I used a screenshot of the Crescent of
Embrace PDFs, blown up to 600%. The line connecting the tips of the red maple
crescent in this screenshot covers 448 pixels north to south and 332 pixels west
to east. Flip these over to get the slope of the bisector (332px of rise for
every 448px of run). To find the angle of this bisector, just solve for A =
arctangent (332/448) = 36.54 degrees = the angle of the red bisector line above
horizontal (east, in Fig. 1). Any rudimentary scientific calculator will have
the arctangent function on it, which can be used to verify this calculation.
Global orientations are usually specified in terms of degrees clockwise from
north, not degrees counter-clockwise from east. Degrees down from north and up
from east sum to 90, so subtract 36.54 from 90 to get that the red bisector in
Figure 6 is oriented 53.46 degrees clockwise from north.
