This is the most incredible visual trick I've ever seen, one that will make your entire reality melt—literally deforming everything in front of your eyes, shrinking and expanding objects around you. It's mind-glowingly trippy (WARNING: Don't try this if you are epileptic. It may cause seizures.)
Have you ever wondered what the visuals look like on hallucinogens? This isn't far off (um, I've read). This is not an animated gif, and nothing is actually moving. It's all in your head. Your trippy, trippy head.
