Optical Illusions

[Spirit Dragon]

Post some optical illusions here. I'll start.

Stare at him and don't move. Soon it will look like a second Knuckles appeared and is walking away. Cool Huh?

 

[Chaos Knux]

...Right...How about something that ISN'T a SRB2Riders sprite?

Stare at the center, it'll spin.

Oh sh*-! ...Not again, man...

Here's another one.

*That's short for "shortcakes".

Neither of the "optical illusions" do anything for me. What am I doing wrong?

 

[Wombatwarlord777]

Just stare at 'em for a longer time. I wouldn't try to focus on any particular spot too hard though.

With the first, I think you're supposed to move your head forwards or backwards as you're staring at it, otherwise it won't do anything.

With the second, just staring anywhere will make it appear to move for a few seconds.

Actually MI, you move your eyes around the large center bubble, and the lines part moves.

I saw one where if you stare at it hard enough, it'll turn into an Animal Collective album.

Stare at the dots in the center for 30-40 seconds, then look at a wall and blink several times. You'll see an image appear while blinking.

That's more of a temporal retina burn than an illusion you can get with any contrastful image, though.
