1. Purple Illusions
This illusion works on about a hundred levels, and the human brain can probably only process six (note: we’re not scientists). You see the lines up there? The slanted ones? Well they’re not slanted at all but are perfectly straight. Get out your set square if you don’t believe us. You do have it with you, don’t you? The colors and shading fool our eyes into thinking the lines are crooked. What’s more, if you look at it one way, it appears as if three-dimensional tiles are emerging from the screen. Pretty cool.
2. Sea Sickness
If you want to induce nausea but don’t have time to get on a boat, why not simply stare at this design? The appropriately named Sea Sickness disorientates you and sucks you into the void. We can’t stop staring at this and are worried we might be being hypnotized. Must… continue… list…
3. Dot Magic
On the surface, this seems quite a simple design. But what color are those dots where the lines meet? Black or white? A lot of these designs rely on affecting only your peripheral vision, which is why every time you try to focus on the color it changes. Something weird is happening, but you can’t quite put your finger (or your eyeball) on it…
4. Hypnotic Spinning Spiral Optical Illusion
This is a really cool one (though not iPhone–sized, it’s worth manipulating). This trippy spiral effect draws the eye to the center, letting the outside images ripple and dots of color appear and reappear. This is the wallpaper equivalent of 2001: A Space Odyssey, though you probably shouldn’t stare at it for too long or you’ll think your iPhone is Hal. And it’s not.
5. Green Dots Optical Illusion
As you move this trippy image around, the colored pattern seems to ripple and move, like a tasteless carpet soaked with mind-altering substances. The pink crosses are placed at specific intervals, to make it seem as though certain areas are coming out at you. The human brain can be fooled quite easily, it seems.
5. Optical Illusion (cogs)
The word you’re looking for is “Whoa!” There is honestly no animation going on here, though it really looks like the wheels are moving. This incredible illusion is a true work of art. Stare at any of the circles individually and it will stop ‘moving’. But, all the others outside of your focus will seem to turn. Things like this make you question whether you can ever believe your eyes!
