I came across this interesting site http://www.bitstrips.com, where you can create comic characters, and comic strips of your own. I guess it gives you ample opportunity to even teach children through comic strips.
You can also use it to put your message across in an interesting and funny way. It need not be related to academics, but it can range from a variety of topics like humor, politics, drama, news, pop culture, and so on.
Take a look at the one I created!
