I wanted to try out this 3D filter, so why not do it on ponies?

Suggestion for those who don't have 3D glasses/monitor
Follow the viewing method in the beginning of this video

and make switch the 3D mode to No Glasses, and then Mirror Split.

It works well enough, and you can still view the video in full color!
