I have nystagmus (rapid, uncontrollable, rhythmic eye movements), so I couldn't see anything at first, just lots of small dots. I had to zoom in (Mac accessibility tool) but then I could see the effect briefly. My eyes go everywhere, but I could see patches of moving shapes with stationary shapes further away, only that the patch moved around a lot!
