Yes,  it's finally election day, and you now can vote for your favorite 10 contenders for the MIT 150 Exhibition. The polls are still open--in fact, they're open until January.  The early leader is the fabled Baker House Piano Drop, because we grandfathered in the 400-some thumbs-up it received. (Why aren't other living groups competing for this record?) Second at the moment are the 1970 Grateful Dead concerts. Then come the Glass Lab (below), Project Athena and Building 20, which no longer exists.  Okay, what are your favorites?
