In the past few years, we have covered plenty of neat “impossible” illusions here. This Infinity Cube Optical Illusion Sculpture is also worth a look. It is a handmade metal desk toy that gives the illusion of floating. It is made from a 10mm bright mild solid steel bar welded together.
This infinity cube measures 12cm x 12cm x 12cm. You can find out more about it on Etsy.
