I only found Legostar Galactica quite recently, which is odd, because it's a Lego-based webcomic that's been around for four months longer than Irregular Webcomic!, and it's been a regular updater, five times a week, ever since.

I've gone through the archives, and burst out laughing many, many times. If you like my comic, I think you'll like Legostar Galactica. It's the story of a space crew who wander around the Galaxy, getting into all sorts of adventures and science fiction parodies. Check it out.
