This is a really cool art idea. Flickr guy "Hawkstudios" takes pictures and then draws a little miniature version of himself in the picture. It looks really cool, but it's also a really clever and fun way to practice drawing different perspectives, lighting effects, shadows, etc. I may have to try and start doing this (although obviously in a far cruder fashion, considering the difference in our levels of talent.)
I really like his style, too. Very clean; cartoony but not sloppy, with lots of character.
Oh, and I want these gloves of his.
