There was a 'Draw Mohammed Day' this week; if you go to Jihad Watch, you can find some samples, along with links to articles explaining why freedom of speech and the press is so important. To give you an idea of the flavor, here is one cartoon and here another. They range from a stick figure entitled 'Mohammed' to unambiguous political cartoons aimed at the 'Islam is a religion of peace' mantra.
Pakistan has already responded by blocking Facebook and YouTube for carrying the cartoons.
Here's my favorite image; although I admit it isn't exactly a picture of Mohammed, it is in the spirit of the event, and is inspired by David.
