Inspired by
Starscape's Quick-Fire idea, what about an
'exquisite corpse'/picture consequences style game running alongside the main challenge? Say, for example, the first theme is 'Starfleet starship' - someone would draw a bridge, the next a primary hull, the following person would draw a secondary hull, then nacelle pylons, then the last person would draw nacelles. Then someone with a working knowledge of Photoshop (or similar) - i.e. not me, although I could possibly fumble something together in Paint - could put all the parts together and post the finished ship? The theme could run for a month so there'd be a fleet of mismatched starships at the end of it. Then the next month could be 'alien' or 'uniform' or something.
I'm imagining quick sketches for each stage in the game rather than detailed masterworks, something that doesn't take any longer than 5 or 10 mins to do - just something fun!
