8 years ago As mentioned in #49 , I reckon a photographic backdrop holder with paper spool would be a good idea, remove the paper spool and add a metal bar and possibly an additional side piece for the middle and then aluminium foam-board seems to be all the rage for backgrounds at the moment, I've used it and it is pretty brill, lightweight but strong, you can print onto it, or paint/draw.
You can also get it in bare metal if you ever wanted to try electrocuting it to see if that left cool markings and wasn't horribly dangerous in an uncontrollable way (if you earthed the panel so the foam didn't come into play so much you might be able to draw with a Tesla coil, and change the tone(?) so it sang or sounded like weird speech. I've got no experience or basis for thinking this beyond you tube and an A Level in physics that I got a D in, so not qualified to tell you to shoot electricity at things and bear no responsibility if anyone tries it without asking someone more knowledgeable first,
Just realised you could just use aluminium sheet for the zapping, and the foam one for regular stuff.

Needs to be large (around 2m x 2m), stable, have a smooth surface and allow attachment of polargraph mechanism and paper roll mechanism if used.
A folding exhibition stand (e.g. http://www.ebay.co.uk/itm/Fordable-Banner-Pop-Roll-Pull-up-Sign-Exhibition-Display-Stand-Show-W-PVC-Screen-/281317070231?hash=item417fcdd597:g:qg4AAMXQyY1TVjNq) could be part of a potential solution, but needs further investigation.
