Didnt work for me.

Only a tinsy bit of the sky went a lil bit blue.

are you sure you looked at the dot for 30 seconds while the screen was in that funny blue and orange mode?
Btw you're still supposed to look at the dot when you put your mouse back to the black and white pic, because that's when the whole pic turns coloured.

Oh yeah, lol nice

The grass was green n the sky was blue but only for about 3 seconds.
