Found this on Tumblr.

 

Seriously, look at the picture (open it in a new tab if you need to, it's a gif). 

It looks better if you open it in a new tab, anyways. 

 

Then, put your fist in the middle of the picture. It goes faster. 

If you cover the outer edges, it goes slower. 

 

:blink:

Ok ... that is freaky lol

My eyes hurt now, lol. That's really cool.

This picture makes me do bad things.
