Am I the only person who recognises the logo for this group as being very similar to the Egyptian Amarna period artistic representations of the sun god, the aten, around 1350BC.
It's amusing that an atheist group has accidentally chosen a symbol which, during pharoah Akhenaten's reign, was used to represent the one true God...which was a massive break with traditional egyptian spiritualism which had masses of gods. Pharoah Akhenaten threw out all the other gods and replaced them with this one sun/sun god and had this symbol carved everywhere he could. After he died it didn't take long for the old gods to be brought back and carvings like this were systematically virtually vandalised out of the historical record.
So..this is the symbol of the one true god, and/or the symbol for the atheistic Brights. :-)
