I think the glyph at the top of the front page of glyph central is different from all the others. Now when I visited the page, the whole image of the glyph did not load (the bottom third was cut off). Or maybe this was intentional; the image is actually of a cut off glyph and we are supposed to decipher the missing part. I could be dead wrong about this, but it seems to me that there are eight glyphs.
