Great..

Was amazing but ShemnonPie.. you must not have done it right if it didnt work.. it will always work but you have to be smart............

Didn't work too well.

I saw that it was black and white straight away. Not the best optical illusion, but it wasn't bad!

I figured it out!

It turns out that the second picture itself is black/white, and that staring at the colors before makes it look colored for a while. In other words, it doesn't really change to black and white, but instead is always that way!

Knew ths one...

I knew this one...and it doesnt just turn black and white when you blink. It also turns like that when you move your eyes.

not bad one

that was an alright game. it was pretty simple overall, but it was a decent time killer. i think i would've enjoyed this one a little bit more if it was a little more challenging overall though.
