This mind-boggling 3D box creates a different illusion from every angle.
Sage Hansen, 29, created the video from his home in Texas, USA, on December 10.
The footage shows a 3D printed object that looks distorted from most angles but aligns to form a perfect cube shape when viewed from one correct angle.
Sage, a 3D animator, said: “I created a virtual cube and camera angle in my 3D software.
“I then started to draw lines at random positions and angles until they aligned in the camera’s perspective.
“I then extruded the lines to make them thicker and rounded off the corners to soften the lighting. I then printed the object on my 3D printer.”
The 3D designing took Sage around two and a half hours per cube.
He added: “I have always enjoyed seeing forced perspective chalk art.
“I like to use my 3D printer to create custom birthday gifts for my friends and family.
“I got my first 3D printer in 2014. The printers have come a long way in a short time and they have made many improvements so I got my current 3D printer in 2016.
“This idea for the illusion cubes came to me in the middle of the night and when I woke up and started to search online and didn’t see this, I knew it would be a fun challenge for me to create.”
