Stare at the black dot on her face until the picture changes.



Unless I've uploaded the .gif wrong somehow (which wouldn't surprise me) you should then be seeing the wonders of afterimage =D Slowly realize that the second picture is actually completely monochrome.

Though it looks like the image might start out at gray sometimes. I don't know how to fix it, just wait for the gaudy inverted-colors version.


Saw an image done this way (might have been from Reddit; my brother found it) and it looked so interesting and so easy that I had to try it, lol. I made one of a better image photographically, but this one seems to give the strongest effect.
Now that I've got that out of my system I can go back to writing like I really should have been doing. Enjoy?



EDIT

It actually yields better results color-wise if you focus on something off to one side of the image instead of the image itself. For example, pick a word under it or soemthing and stare at that until the picture changes, then observe the effects. I don't know exactly why this is happening-- as far as I know the highest concentration of cones (which sense colors better as opposed to rods) is in the fovea (center of your field of vision, sort of) so the effect might be expected to be stronger there instead. It could just be because I've been staring at this for quite some time though. Either way, pretty intriguing. The instant I get a Reddit account this is going on there.
