I was reading and old issue of Live Design and caught a reference to a piece of software called Watchout. I have not used it, but it looks like it would be cool - and a great tool for doing projections. Its geared towards multi-screen productions & 3D mapping, something that is increasing in popularity.
Media and technology behind it are here to stay - at lease in the foreseeable future. What I have learned in my recent projects is that there are in and outs to the process behind creating digital designs that don't directly transfer to the way that we typically design in theatre.
