;) :D

It didn't stop even when I looked at the black spot:eek: :eek: :eek: :eek: :eek:

:cool: :cool: :eek: :eek: well yes amazing.
could it seem to move due to the screen frequecy??
:eek: :eek: :cool: i will leave my sun glases on!
:cool: Fiona

Fiona: no, since the screen refreshes more frequently than your TV (twice as much, up to 5 times - depending on screen and TV). You won't notice the screen refreshing.

If you aren't sure, print it :)

But Daniel, everything stays still when you print it!:D :D :D

Well, I didn't try :)..but I don't see why a hard copy won't produce the same illusion.

Different hue/luminance (and possibly saturation) values?

(How) does it affect the illusion?

Maybe you need to print it on super high quality prints!

Cool one!
 

Thanks for sharing Susan!

This one's going to make a round trip on this little old planet in no time!

;)

Colour and light. It's what affects the eyes.

I printed the hard copy last night and it hardly worked at all. Now it's resting in the sun light it's doing its thing a little faster.

If the illusion is printed from a printer that doesn't have good colour quality then the quality of the ilusion is affected. If the electric light is not intense then the same thing happens. Sun light has the best qualities. On screen the illusion works perfectly because of the colour brightness and light quality of the monitor.

Think of the brain washing it could do if it was wall paper in one's house :eek: :rolleyes:

Nice one Susan ....very impressive! ...I wonder how well it would work if printed (high quality) and then illuminated with a spot light. It would be a great talking point if it were framed on a wall in your home.

edit: PS, It seems to move less when I turn down my monitor brightness.
