We, (the TechnoKats) all did the same thing for New Years.......awhile back our community asked us to build them a "ball" similar to times square that could be dropped from the side of a building in our city's square, so we did it. Every year now we set up this ball and run it to simulate the events that go on in Times Square and to ring in the new year.
If u ask me its pretty darn cool (even though i was a little disappointed that the city didnt have fireworks this year

)
A picture of the ball can be seen in the attached jpeg file.
(the lights may look funny in the pic....but the lights on the ball can do different sequences and patterns)
WARNING THE PIC BELOW IS AN OLD PIC AND IS NOT CURRENT!!!!! MAYBE I CAN GET A NEW ONE
