Bored? Got a printer?

Time hanging heavy at work (or indeed at home) today? Wish there was something else to pass the time other than surfing the web and reading all those tedious blogs?

Just print out the picture below and cut out the isolated diamond. Now lay it on one of the top row of diamonds. Now move it to the one of the diamonds in the middle row. Now to the bottom row. Notice anything?

That's got you baffled, hasn't it, you credulous simpleton?
