Can anyone tell me about the illuminati cross, I think it is the cross with the "all seing eye" type thing in the center.

Ask this in Paranoid Delusions, you'll get better answers there.

The illuminati have a lot of different logo's, like the Eternal Flame (the Light Lucifer gave them(For example the Olympic fire.)). And the Pyramid with a human eye in its top, representing the All seeing Eye of Lucifer.

I'm pretty sure that these assholes are real though.

It might be the upside down cross... or is that the devil? Maybe it's both.
