Chessboard & cylinder
Aug. 19th, 2008 11:20 amThere was a man in the post office this morning, a big, leathery, builder type in work shorts and a checked shirt, and he boomed to the lady behind the counter, "I've got to send this to my grand-daughter, love!" and he pulled a tiny, pink, fairy dress out of a shopping bag. So that was cute. And then another man came in wanting to post a chainsaw (in a protective case), but by that time I'd been served so I didn't get to see if he was allowed to or not.
Someone forwarded me one of those "THIS IS INCREDIBLE YOU'LL BE AMAZED!!!!!" emails the other day, which I don't normally encourage. This one, though, actually was kind of interesting: it was full of optical illusions. One in particular caught my attention:
The point of it is that square A and square B are really the same colour. Normally once I hear the explanation of an optical illusion, I can see it, but this time, while I understand it in theory, I've been looking and looking and looking at it and I can't get it. Even now I've seen the little animation on this page, my brain just won't accept it.
( And a game! )
