A bit disappointed that the arrows are not what is driving this (see other comments). But would it be possible to have a "semantic optical illussion"? Was any

  I thought it might be the arrows creating the illusion, so I covered them with my thumbs and it still worked.

  Something like the lines with different arrows? If not, please refrain for inventing cognitive hazards until 2021, please. https://gpuzzles.com/optical-illusion/length-of-lines/ https://gpuzzles.com/optical-illusion/length-of-lines/

  It's possible to suggest a direction for the spinning dancer illusion.[1] I don't have an example for you that actually has cues included, but you can do it with some success in your own mind. Decide you want to see it spinning clockwise, then look at it. Now look away, and tell yourself it's going to be spinning anti-clockwise, then look at it again. I now that's not quite what you wanted, but I imagine you could achieve a similar result by showing a clockwise/anticlockwise cue on the image itself.
