There's a new Humble Indie Bundle up, comprised completely of Frozenbyte games. The rules are the same as the previous two HIBs: Pay what you want ($1 minimum); you control how much of your $ goes to charity and how much goes to the game developers; cross platform games (Mac, Win, Linux); Steam keys included; no DRM. I heard on reddit that the some of the Mac games are not currently listed on the Steam store, but if you register your keys, you will be able to download them. Handy. This deal is worth it no matter what, but especially so for Trine.
