This was created for the first 48 hour animation lockdown I took part in during 2011. This was actually the second animation I've ever created. With the theme being pixel art, my team (named 8 Bit Ninja) chose to make something inspired by that famous matrix ping-pong skit from a Japanese game show.
The original audio I used for the ping-pong match was a licensed song, so I recently had my sound person redo that audio. I also made a few other minor tweaks, but the animation otherwise is left unchanged.
