After stumbling on Hourly Comics, I decided to try my own yesterday. The premise is simple: for every hour you're awake, you draw a comic. You can click to enlarge the whole thing:
It's a fun constraint; I had to put off going to the video store and getting dinner to make sure I got in under the hour, and also figure out how to discreetly doodle at work. I'm pretty good at that, though.
Hourly Comic Day is Feb 1. That's Monday! Try it!
