I've recreated the illusion in 139 characters* of Javascript: https://www.dwitter.net/d/14459 https://www.dwitter.net/d/14459 * Dwitter has a built-in `R` for RGB color, `S` for Math.sin, and `x` for the 2d context of the canvas.

This is amazing, Bravo. I found myself fascinated and just staring wondering when that diamond would get to the top. I wonder if this might be used for loading/waiting transition assets on apps/websites.

Does anyone else not perceive motion in this? I can see the background color oscillating, but the foreground figure remains stationary. Viewing it on an iPhone.

  Perhaps the iPhone is scaling the image down so much you lose the thin outline around the foreground figure? Try on a tablet or desktop.

  i didn't really find it compelling until the point in the video when they change the direction

  Can you see the edges between the diamond and the background? Typically, the motion occurs when you can see the edges, and disappears when you are far enough away to make the edges too thin to be seen.

Would it appear to be fixed in place if actually moving down the screen?

  I don't think so, for me the illusion is not just uniformly upwards throughout the cycle, but also includes a sudden downward shift, so its more like sawtooth motion illusion., so if it were to move down I predict it would look more like a somewhat static diamond jumping down in steps... it would be interesting to try in order to determing the exact illusory motion profile, if it doesnt seem static between the jumps but seems to wiggle up and down before jumping... Edit: if someone would try this, I would recommend using a larger diamond with thick enough edges and viewed from a distance such that pixelization effects are ruled out...

  no, it still appears to move, BUT it can appear to move at angle if the diamond's movement is to the left or right.

Very cool!
