We just finished a great piece in San Francisco for the Creators Project alongside Chris Milk.
Using the new Microsoft Kinects for Windows, Unity, and open Frameworks, we created three 25 foot installations that spanned the entire width of a huge hanger. When someone walked in front of each of the 3 pieces, one of 3 things happen- your shadow disintegrated into ravens, your body got eaten by ravens hitchcock style, or you became a raven.
This is a quick look at some rough iphone video. We will be having a nice clean case study soon.
