I mentioned already the current trend of writing live coding tools. During the Tokyo Demo Fest, which was taking place last weekend in Akihabara, Hole performed a live coding with his own tool, thus VJ-ing while the DJ was on stage. Interestingly, this led to collaborative coding when someone joined him. This could be a very interesting direction to explore.
The tool, LiveCoder, looks pretty clean on big screen and may be worth trying out.
