Pseudoscope Effect - 3d Triangle illusion

With red/cyan 3d glasses, notice how the two triangle objects seem different in depth. They also appear to move in opposite directions.

The left video is in Reverse 3d. The right video is identical but in true 3d.
The video on the left shows what we would see looking through a pseudoscope.

Sometimes our mind refuses to see the triangle reversed on the left.

Yeah that’s right. Although when looking through a real pseudoscope it’s more difficult to see it non reversed. I also made a cube version, see the link in description.
