This is a preview of a new physics game in development. It just won an award from the Independent Games Festival. I love these simple and thoughtful games that use computing and technology to challenge you in ways that other modes of interaction could never achieve.
In the same vein, I just finished playing Portal, which is a great twist on the first person shooter mode of gaming mixed with a puzzle game. And the pay off at the end is priceless (caution: contains spoilers). Portal is included in Valve’s The Orange Box, a great value for any computer gamer.
