Hi Lee, Once I get CVS up and running and a copy of the source, I can look at some ideas that I have for updating the screen every second rather than every pixel. There would be a massive improvement in speed alone. There are a number of optimisations that can be performed if just working in RAM rather than to screen.

Maybe Paul would like to try optimizing some of the display code? Its coded for "simplest thing that could possibly work" right now, not for speed.
