Scientists from the University of Sussex are developing a method of displaying 3D tactile images using ultrasonic waves. The system works by levitating a small plastic bead and rapidly maneuvering it to create a persistence of vision effect. If they can move more dots or move them faster, they could create more complex images.
Canadian camouflage experts Hyperstealth Biotechnology has recently applied for patents on their technology which can bend light around an object to make it vanish from sight when placed in its sweet spot. The paper-thin screen could be used to hide military targets from ground-level threats. More on Vimeo.
Intrigued by slow motion visuals? Wonder Machines‘ unusual picture frame makes real world objects appear to move in slow motion. Designed by artist and inventor Jeff Lieberman (Time Warp), the device appears to use some sort of nearly imperceptible vibrations to pull off its trickery.
Latheman’s crazy machines made what he calls the “impossible screw.” If you hold it sideways, it will turn only clockwise. It doesn’t matter if you flip it. The only way to get it to turn both ways is to hold it upright. It’s a fun trinket that you can replicate with a hacksaw and a file.
Take a look at the video, and you’ll swear that these balls are spinning in a circular orbit. But look more closely, and you’ll see that each ball is moving along a perfectly straight path. The mechanical model is based on a design by 16th century Italian poymath Girolamo Cardano.
Using a professional full-color 3D printer and taking advantage of the stairstepped surfaces of voxels, Make Anything was able to create a sweet model of a human skull that appears to change colors when viewed from different angles. Download the model here.
Ellusionist took the technology from its wrist-mounted flash gun and incorporated it into a marker pen. The Pyro Fire Shooter Pen looks like a Sharpie and actually writes, but press its covert button for 3 seconds, and it will ignite and shoot flash paper over 10 ft.
Magician Eric Chien won the 2018 FISM Close Up Grand Prize with this amazing series of tricks. He uses a ribbon and two rectangles to transform playing cards (and his vest), swapping their colors, slicing and repairing and ultimately turning the cards into coins.
An amusing clip from the Netflix series Magic for Humans in which magician Justin Willman uses a mix of illusion and collusion with the audience to convice two subjects that they are now invisible. Lots of commenters think the marks were actors, but we’re not so cynical.
Maker of things Izzy Swan shows off a building technique that makes it look like layers of wood have been woven together into a form that should be impossible to pull off. We won’t give away the trick, but it takes a whole lot of work to pull off the illusion.
John Muntean shows off his amazing LEGO shadow sculptures, each of which looks like an amorphous blob, but casts shadows of three distinct images as it’s rotated through a beam of light. After DragonButterflyJet, be sure to check out KnightMermaidPirateShip and ABC.
