I didn't make the video, or the animation. Credit goes to Black Gryph0n; see link to his channel below.

Pinkie breaks so many walls with this one, it's hard to keep count.

3D TIPS:
A 3D monitor or TV is the best route, but most of us are still stuck with red/cyan glasses. In that case, try Youtube's "optimized" or "grayscale" modes for the best effect [as ugly as they may be.]

Just wanted to point out, this isn't some cheap trick I put together in a minute. I actually had to isolate each element manually frame by frame, add virtual cameras, and export video for both the left and right eye. Took most of the day.

Be sure to check out the original video maker's channel, and give him a sub for the amazing and funny video!
