Penrose Triangle

This is a drawing of a Penrose Triangle.

It’s an impossible shape — its topology is such that it can’t exist in the real world.

Except in Perth, where there is a real live Penrose Triangle. Here’s how it looks on Google Maps.

Many people drive past it every day, and no doubt they think, “What an ugly sculpture.”

But if you see it from the correct location, the legs seem to converge, forming the impossible triangle. Here’s a picture I took over the weekend.

Neat, eh.

The Wikipedia page has more information for the curious, including pictures of the shape from other angles.

Horse and rider puzzle

Sam Loyd might have called this a ‘pretty puzzle’. I don’t know where it comes from, but it’s one of my favourites.

All you have to do is arrange these three pictures to produce two identical pictures of a horse and rider.

If you click on the picture, you’ll get a larger version that you can print and cut out. The lines themselves don’t figure into the solution — they’re just there to show you where to cut.

You don’t have to tear or fold any of the pieces of paper. At least, the solution doesn’t rely on those kinds of tactics. It’s really quite straightforward.

Keep at it!

UPDATE: Found the source of the puzzle! It appears there’s a patent for it. Check out the original drawings here.
