watch your hand grow...

Cenesthetic Hallucination

This is cool. When you're done with the 30 seconds, look at the back of your hand while it is still on the mouse.
Be sure to click on the click here box to start the full screen display.

Follow the directions

You have just gotta try this!!! Make sure you look at the image for a
full 30 seconds before looking at your hand! Have fun!

Okay, this is downright weird. Don't be suspicious, nothing is going
to jump out or scream at you. Just follow the instructions. Wait the
entire 30 seconds.

1.- Open the link
2.- Then "click me to get trippy",
3.- Look at the center of the screen for 30 seconds, and then..
4.- Look at your hand holding the mouse, without moving it away from
the mouse..

NOT BEFORE!

(it is no joke, it is called "cenesthetic hallucination")
