Been working hard at using water as an interface, finally made some positive steps in that direction this afternoon. The first thing is a video of a mock-up of the actual patch that uses two video sources. The real patch uses a webcam on one side, but it was hard to make the video and move the water at the same time, so I made a quick recording of the water and used that recording to show the processing. The patch takes two sources and uses the method of lumakeying to blend them. A lumakey essentially takes all the pixels within a certain value of one video and makes them transparent, thus revealing the second video behind. So here's the video of the screen shot:
And the second is a video of the result projected on to a 4x8 piece of black burlap from about ten feet away. It makes the weird masking decision on the previous video make more sense:
