I have been giving RWP challenge some thought. The swastika thing is just too crude and not in line with the Darwin fish. The problem is that Islam has no real symbols. IIRC they are forbidden, but there are some things that might be used. I am terrible at art so maybe some of you can push one along.
1. Seven veils with alluring dark eyes above each. In a circle. In the center, a bomb. Words "There are 65 more where we came from. We get the 72 virgins and the dance of the seven veils together and a bomb.
2. A crescent moon and star are typical (see Green Crescent Society - version of Red Cross). Add a couple of handles and you have a hammer and sickle.
3. Years ago, there used to be a trucking company with a running camel on its side (maybe others remember this, too). It's motto was "Humpin' for you". I always thought this had possibilities.
4. A flying camel with wild Abdul on its back flying toward a skyscraper. Message "Delivering a message of peace from Allah".
5. A picture of Osama. Pointing to you and in the other hand, AK47, grenade launcher, belt of explosives. "Uncle Osama wants you"
Surely one of you creative geniuses can make something of one of these.
