Jason is up to his 'camp' for our share of the great Impetvs demo for NATCON 2011. So here is what I have managed to acheive so far. It is less complimacted than I originally envisaged but I think I can make this servicable in time for Friday. Pity I still have a lecture to write, marking to be done, no office... But enough caterwauling - on to the 'to do' list.
