OK, this has nothing to do with BJT's at all, but I just thought it was too cool not to share with my friends here. http://www.youtube.com/watch?v=yjbpwlqp5Qw You'll need to crank up the speakers for the first two minutes of it, then back 'em down for the remainder. Note that this choir uses absolutely no instruments other than their hands, feets, and voices. Watch the guy simulating the percussion section - don't we all wish we had that level of focus & concentration near the end of a BJT round?
