At first sight, it’s just a signpost in the Swiss mountains, with lots of tubes attached to it, and that’s because that’s exactly what it actually is.

But brilliantly, those tubes are so arranged, that when you spy through each of them, you see a different mountain.

Then look on the side of the tube in question, and you can see exactly which mountain you are looking at.

This makes mountain identification – previously rather tricky, one would imagine, looking at just how many tubes are attached that signpost – much, much easier.
