I think one of the most interesting things about the muhammadoodle controversy is how recent it really is. While Islam has technically always been against depictions of Muhammad: [link]
well...mostly against it: [link]
there were still several depictions of the prophets in Europe, many of which are ore insulting than some of the things produced today: [link]
I think the biggest reason we even have this outrage is because it's entirely impossible to be a modern civilization. Back several hundred years ago, someone would be able to draw as many muhammads as they want and there was a good chance that they wouldn't leave that person's home or that it wouldn't be seen as such great of a controversy: [link]
It seems to me only recent that there's been such a strife going on outside of purely Islamic areas. And if you ask me, I'd say it's because Islam (at least in it's absolute purest form) is having a hard time adapting to modern world.
Another interesting thing I've noticed is the various similarities between the depictions of Muhammad. The fact that he's always dressed in stereotypical arab clothing and sporting a beard (unless he's in Hell: [link]
) makes him look more like his followers: [link]
if anything. Hell, you probably wouldn't know that those were pictures of Muhammad unless otherwise stated. In actuality, the most recognizable picture of Muhammad I've found to have ever been made seems to have been the Danish cartoon's depiction of the prophet with a bomb on his head: [link]
Just something to think about. The website I linked you to several times has many different portrait's, statues, cartoons, etc of Muhammad. It's a pretty interesting place to visit if you want to see how Muhammad's image changes from place to place in different times.
