Here is mine....about 100 color changes in roughly 29 seconds. I say about a hundred because 1) the second deck is not a complete deck and 2) I messed up a little bit on a few of the changes and the method is visible. I'm hoping/praying that this doesn't invalide my entire entry, but only those few changes, which takes the number down a little.
On a second note, while this is a serious entry in the aspect that it'd be cool to win, I know what I'm performing here isn't
really a color change but more of a move with a specific camera angle...well, it's sort of just a ridiculous idea, but I had fun with it, and I laugh when I see the video. Again, if my entry is invalidated, well, c'est la vie, but ya never know
Third note: changes occur from 0:19 until 0:48.
Fourth (final, haha): sorry for the size of the video. I don't actually have a video camera other than my mom's iPad, which does shoot video, but sometimes the video size gets awkward.
