Here we go, it took some time, but I created this in The GIMP, where I've been playing around with animation a bit lately. The ZAP (on Zappl) can be found here, but I'll also leave a copy here of the smaller version of the animated GIF which I created for this contest. You can see the full sized image on Giphy.com. I had some real problems trying to upload this thing, and I had to keep on reducing the size, but in the end I got it working.
