I suppose improv is by its nature experimental. But what we're thinking of here is the stuff you haven't tried before. Got a new form or game you want to try? Want to put together a team of people you've never met? Maybe a set in Swahili? Actors in blind folds? Smellprov? I'm just throwing out ideas here.
If you or your team want to try something a little different, drop us an email at email@example.com. We'll set aside a slot during our experimental blocks in the later hours either Friday or Saturday.
