I think we should do a SNC based around presentation. Inspired off of Derren Brown's Enigma, I think we should have a list of possible basic tricks or plots to select one from, and from that one create our own presentation or spin on it. Just saying...
Or even just one trick, sometime simple that everyone knows or could learn quickly (possibly something with a free tutorial to view) and then give everyone a few hours (or a whole day) to come up with an awesome presentation.
