Barack Obama Optical Illusion | Celerity optical illusion

Just like with the Jesus Illusion, you'll stare at this picture for 30 seconds and then stare at a blank wall. The wall doesn't have to be white, but we've found it works better with lighter colors. You can also stare at the white space next to the illusion on your computer monitor, or at a blank piece of paper on your desk.

For you to experience the strongest illusion, you'll want to stare at the center of the red plus sign. Don't move your head, and really try not to move your eyes at all. We've found that a plus sign allows your eyes to move ever so slightly, but you should be able to keep them centered.

Cycle Illusion | Motorbike Shadow Illusion

What do you see in this picture? A bicycle? But when you move far away from your monitor, you will see the shadow of the bicycle form a motorbike.

Flickering Fog Illusion

Just like you did for the other Illusions before, stare intently at the red dot in the center of the left block for about a couple of minutes. Once you've done this, look over to the center of the right block. It should act weird - by fading out and 'flickering'. If you move your head closer and further from the monitor (while focussing in the center), you should see some interesting interference effects too.
