Replying to Rotoscope

Does or has anyone here ever done rotoscope?  I'm in a video class at college and we did one as a class where we projected the image onto paper and hand drew the frames.  Then I wanted to try one in photoshop.  Obviously its slow going to draw every frame.  These drawings aren't even good or precise and still took me about 20 minutes each.  That's about a week of work into a 2 second clip.

If anyone else has made any post links here if you want so we can compare.
