Russ, GlowLoop projector, glow screen. More on GlowLoop:
The glow screen got a lot of impromptu drawing.
You need a blue laser pointer to make this work. Any blue laser pointer will probably be fine - mine was this one: http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=110583533331&ssPageName=ADME:B:EOIBSA:GB:1123
The paint I used:
Several varieties of glow-in-the-dark paint, in assorted colours:
Anton's spare webcam saved the day
Looks just like a hand.
Leonora with laser, rapt.
Kaspar's OpenCV->HPGL->plotter drawings
Admiring our results

Sketchy's acceleration was set at twice the value we used last week, give less accuracy but more fluid lines.
Russ had improved the projector no end
