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 I don't see why a hard copy won't produce the same illusion. |

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 |

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