Wait a sec... I don't remember saying Wicked. Did someone Change their name to mine!? Or did I just forget thay I said that!?!? :S

Dude! Where do you come up with stuff ? It's the most awesome almighty.
I think ur cul. Do you have a My Space page?
I would like to visit it if you do. Bi.

awesome. kinda boring compared to other types of optical illusions though

awesome! i like the first most. really kinda "here comes the sun" effect. but the second is cool to. seems like the dark is catching you. they're all really nice

that was way fricking awsome

When you stare at an image for several seconds it gets imprinted on your retina in the back of your eye. You can then see it with your eyes shut and when another image is looked at right away the first and second can unite to give a third image of different combined colors. Similar effects can be seen by moving closer to some images you have stared at which combines the near and far images in the back of your eye or merges different colors to give a new color. It is the same as looking at a bright lite for a short time and anafter image remains for several seconds...

HAHAHAHAHAHAHAH!!! HEHEHEHEHEHE!!! so COOOL!!!
I love cheese, and these are CHEEEZY!!!!!
HAHAHAHAHHHAAHAHAHAHAHAHAHAHAHAHAHHAHAHAHA

If you back up far enough, the blotches start getting bigger again.
