Whenever I am bored on the train to somewhere (all the time) or when I feel particularly inspired (at least once daily) I like to draw on my iPod Touch. The program I use is called Scribble. Its pretty simple, and just looks like a simpler version of MS Paint in the palm of your hand. I like to draw animals, and I have amassed quite a collection of them in my menagerie. What should I draw next?
