Optical illusions are designed to fool the human eye, but sometimes, they just don't seem possible. Well, thanks to a few helpful geeks, we get an inside look at how five mind-blowing illusions are accomplished. Continue reading to see them all.
5. Minecraft Illusion Poster
I've been getting into minecraft recently and ya, it's addicting. I know I've made a few of these types of posters before but I thought you guys might enjoy a Minecraft version. I debated on whether to add music or just use the sound fx. Obviously I went with the sound fx. I didnt include any of the actual sound fx because I was a little lazy.
4. VHS Tape Illusion
I was asked by Youtube to participate in their "Play Means Business" Program. They gave me the statistic of "500 years of youtube videos are watched each day through social media sites" and asked if I could build an illusion around it. I thought VHS tapes would be a nice way to portray "video" and would be easy to work with to create the illusion. The only effects added to this video are the words added to the floor below "500 years" at the end of the video.
3. Moving Square Illusion
There are 2 sets of lines moving back and forth perpendicularly but when the paper squares are placed on the screen the lines suddenly appear to be a square moving in a circular motion. I've seen this illusion for a while and have always been impressed by it. I wanted to try and create my own version.
2. Chair Illusion
I created this illusion by placing a chair in the middle of the room and shining a bright light on it which created a shadow. I cut black poster board and taped it so that it covered the shadow. Then I moved the light source to the opposite side of the room and shined it on the chair which created another shadow. Again, I cut black poster board and taped it so that it covered the shadow. Then I just removed the actual chair from inbetween the 2 shadows. The whole process took about 10 hours.
1. Shade Illusion
The illusion works because of the "shadow" that falls on the checkerboard. Lets think of the square that the shadow falls on. Now picture that the shadow doesnt exist, you would see a light colored square surrounded by the dark colored squares. But when the shadow falls on top of that light colored square, the shadow causes the shade to become darker but it also causes the surrounding darker squares to become darker. So within the shadow region the brightness and darkness of the squares are still relative to one another. But they are no longer relative to the squares that lie outside of the shadow.
