This is interesting - I found it via Evil Hat's blog.
Technoir is a rules light game set up with the sort of cyberpunk and hard boiled roleplaying, using a rules-light system using tags. There's a Kickstarter that's already made it's nut, but there's also a Website for the game, where you can download the beta version of it.
If you do nothing else, check out the vid that Jeremy Keller made for his kickstater - it's really good.
I'm not certain I'm going to buy into the kickstarter yet, but I'm considering it.
