OH MY GOSH!!! i saw it for the first time evvvver today!!!!!!
i went to the website you linked, supermouse, and i followed their instructions for a while, and then i saw it!!!! i saw just some lines at first, like they were the outlines of something, and then i titled the picture, to figure out where the outlines of the rest of the picture were, and then i saw the shape of a cow and a cactus and stuff, but the colors were the same as the picture i saw before. the whole thing was completely different than what i thought i was supposed to see before…
i highly recommend them. they have a picture, with two dots on top of it, and when you see them as three, you’re at the right place.
my problem before was that i was blurring my eyes, trying to look “through” the picture, like Harp’s suggestion, and most poeple had suggested to me in the past. what you need to do is put the picture so close that it touches your nose, and then focus on it, and keep focusing on it while you bring it away from your face a little bit. that’s what worked for me anyway, good luck everyone!!
