The Japanese anime style is very eye catching. I recently found a site with linearts for coloring:

Now, there are lots of sites that teach you methods of coloring these with Photoshop or other bitmap apps, but almost none using vector programs.
So I decided to see if it could be done. The one below is pure vector. A bit harder and the fills and effects are not as spectacular as what you can get with a bitmap app, but I can resize and rotate this thing any way I want.
