PowerPoint karaoke
A really fun event at the ACRL conference in Philadelphia this year, is Battle Decks. It involves participants presenting PowerPoint presentations they haven't seen before! Five or six participants compete for a grand prize (an iPad, of course) by "talking to" a library orientated presentation consisting of 10 slides. They have to do this in 5 minutes and are judged in categories, such as flow, audience participation, completion, etc. Hilarious stuff!
