What is this? Should I be able to recognize it, or elements of it? I'm not half-bad at the science fiction and fantasy trivia thing, and this is just driving me nuts.
The logo is an original creation, but it may be inspired from middle icon of this image:
I discovered this accidentally on Wikipedia pages of Weapon of mass destruction and Nuclear weapons testing. In the image, it appears along with nuke (denotes radioactivity) and danger (denotes toxicity) symbols.
The symbol has unicode of
U+2623 and is used to denote Biohazard.
Looks like designer of the logo used something from this to his/her creativity juice. But, its just a guess. Only designer can answer this.
