I'm actually a pretty shit animator, I've only dabbled in posters, never really tried to do anything like this, but hey, there's a first time for everything, right? If we can spread the Idea maybe a more experienced animator could do it, rather than me lol.

Maybe we could do something like the Conga or Kazotsky Kick except where the class would pull out a snare drum and start playing some sick war beats while marching. It could be allclass, and it would add to our TF2 orchestra of instruments. Or perhaps each class might pull out a different kind of drum, like heavy would pull out one of these: http://static.musiciansfriend.com/derivates/18/001/224/281/DV016_Jpg_Large_442837.001.892_blk_16x32.jpg (Don't know the name, sorry) and scout would pull out a snare drum, and If played all together, it would make a marching song.

Just a thought.
