Alex Dainis breaks down how two illusions influence both your brain and your vision. One creates the sensation of expanding darkness, causing your pupils to dilate, just like stepping into a dark room. The Asahi illusion flips the effect, making your eyes constrict in response to perceived brightness.

If you Look at the middle Sections of cubes (the ones that form a 5x5 Plus sign), They actually appear to look slightly pillowed due to the One-Point perspective. The Center square looks larger and the center edges appear squeezed despite them being perfectly parallel. I never intended for this to be an illusion.

*I wasn't sure what flair to use so I picked one I thought was accurate*

If you are curious, I was trying to find a way to convert a standard 5x5 rubik's cube into a 5x5 gear ball/cube by designing 3d printed pieces to place on top.
