YouTube illusion and science channel Brusspup recently did an anamorphic illusion project in which he photographed a few random objects resting on a piece of paper (e.g. a Rubik’s cube, a roll of tape, and a shoe), skewed them, printed them out as high-resolution prints, and then photographed them at an angle to make the prints look just like the original objects.

A couple weeks ago we shared an interesting video in which a speaker and Canon 5D Mark II’s frame rate were used to make water appear to be frozen in mid-air. This new video by YouTube user Brusspup takes the idea to the next level by making the water appear to travel upwards. He explains:
Fill a bucket full of water and place it about 5 feet off the ground. Place a subwoofer about 1 foot lower than the bucket. Run a plastic tube from the top bucket down in front of the subwoofer. Tape the tube to the front of the speaker. Then aim the end of the tube to an empty bucket on the floor. Get the water flowing from the top bucket. Now just generate a 24 hz sine wave and set your camera to 24 fps and watch the magic happen. Basically your cameras frame rate is synced up with the rate of the vibrations of the water so it appears to be frozen or still. Now if you play a 23 hz sine wave your frame rate will be off just a little compared to the sine wave causing the water to “move backward” or so as it appears. You can play a 25 hz sine wave and cause the water to move slowly forward.
This experiment has become quite a trend as of late — this particular video has been viewed over a million times in less than a week.
We often share cool slow motion or time-lapse videos here on PetaPixel, but this video is a bit different. YouTube user brusspup uses a turntable spinning at 45RPM to create amazing optical illusion animations. To a human eye look at the turntable, everything looks like a blur, but record it at 24 frames per second, and amazing animations appear!

The images of the guy jumping is me. I recorded myself jumping in the living room then took 30 frames from that footage and traced the images in photoshop and filled with black. Then printed out the 30 images and cut each one out. I used 30 wooden blocks and glued them to a piece of construction paper then taped the images of the jumping guy to the clear sheet and aligned them with the blocks.
