This is a nice idea – basically, the background never changes but if you follow the moving ‘star’, it will appear to shift.
Does it work for you?

When it goes down the illusion is there for me. When it goes up not really.
Same for me. Unavoidable in the downward direction, really difficult to see upwards.
Same here.
Ditto. Only works for me when the star is moving down screen.
ditto
Me too, but only every third time.
works more going up than going down for me…
For me, the exact opposite.
Cool, but I only get a small patch in the centre moving.
The shadows give the brain an idea of direction. Nice.
Didn’t work for me. Damn you brain!
Very effective, I see the centre patch lurch to the right as the star rises and shudder to the left as the star falls, then I can’t focus properly to read.
I’ve got left and right muddled, the movement is to the right as the star falls and less pronounced to the right on as the star rises. Holiday hangover.
Had to make it full screen to get the effect, and then like some others it was much more pronounced on the downstroke than the up.
Weird! Never trust what your brain tells you!
very cool, only saw it as i looked away from screen.
No. What’s supposed to happen? Nothing moved. [confuzzled]
Yep. It worked for me. How does it work? Something to do with the spacing of the squares? Also, the shading of the squares?
For me it works going downwards but not upwards. Weird.
Turn your screens upside down !
Works equally well both up and down for me but only in full screen view.
moved for me before i even started playing the video, and then that’s when the party started!
The illusion works also with the video stopped !
Use the mouse pointer instead of the star.
The background appeared to move only when the star was going from top to bottom, not the other way.
Only downwards in small screen, both ways in fullscreen for me
Source? Who’s work is this?
Does not work for me. But every now and then the background tried to move but would snap back and remain still.
like water…

I don’t need the star; the background was moving before I started the video. I get this effect staring at my innocent brown and white speckled carpet sometimes… It would be interesting to know why I’m so susceptible to this type of illusion – anyone know if there’s any research on it?
(p.s. Stumbled upon this fascinating blog today, via Derren Brown’s.)
Nothing at all I thought first when it was in the little video window on the blog. But when I made it fullscreen it works, both up and down. Has to be a big enough part of you field of vision i think.
