As a result of the speed improvement I found by using the new Pack and Unpack functions, I've gone the whole hog and compressed all the 2D arrays, the bubble universe animation now runs at 319mS per iteration (better than 3Hz) on my 480x320 LCD Picomite, at 378MHz a not insignificant improvement on the previous of 350mS :-) Still don't really understand why though?
