The Neo-Futurists are perhaps most well known for "Too Much Light Makes the Baby Go Blind", which is, despite it's name, not about infant abuse, but rather is an attempt to put 30 plays on stage in, oh, one hour or so. This is one of those concepts that you really have to go and see to understand, and given that they don't charge very much at all ($7 + a roll of a die, or $8-$13) you really should get out and see them!
Besides TMLMTBGB they also put up a variety of other shows. You'd think they would get bored of doing TML... by now, but actually they keep reinventing the show so it's never quite the same. They also bring TML... on the road, so if you have a large group you can ask them to come in and perform for you.
Their theater, the 'neo-futurarium', is, um, weird. It's not so much a theater as a converted space which they kind of rigged up with seating.
