I did a quick search on the site and didn't find any mention of this indie game that's just about to be released, so I thought I'd mention it and start a thread.
I've been following this since reading about it in an article on Slashdot last year regarding the 2007 IGF finalists. It was the grand prize winner I believe.
Take a squiz at the videos linked below (came from the developers site, bit-blot.com:)
I know I'm going to be trying this one out first thing on Friday.
It's for PC (now) and the developers cite January for the Mac port release.
