I know this may be off topic, but this is so cool!!!
I found this on yahoo news. Someone was sharing some pictures with Illusions.
I didn't save the pics from the article, so I went to Flickr.com which is where they were, and just found the ones that were in the article. I'll just share these with you too!!! : D
If you stare at the middle closely, the red rings will look like they're rotating.
Stare in the middle, and the rest of the picture looks like it's moving.
Stare in the center, and the whole picture will start flickering.
This one is the best. Just stare at the picture, and the leaves will look like they're all moving in a wave!!! : D
