Proceed At Your Own Risk

This may not be safe for all viewers, but the effect is truly hallucinogenic. When you are ready, press the play button and watch the center of this until the prompt comes up to look away (about 1 minute, but 30 seconds will work too.) Then look at something like a painting, a poster, your hand or your face in the mirror. Truly eerie.

May make your eyes wonky for a minute, so don't try this unless your very curious or very foolish.
