About a month ago, me and grigr discussed twisty puzzles and took notice that beside many existing gear puzzles there's no Gear Pyraminx, although it seemed (at least at that time) that it should be the simplest of them.

So I made a sketch and though that I should ask Oskar whether he would mind if I try to design a Gear Pyraminx (because he could be planning it or working on it at the moment, who knows). But not only he did not mind but said that he's pleased that I was pursuing this direction and offered his support.

After I started I found that it would be not a simple design at all, because (as opposed to Gear Cube) the edges were supposed to roll between two unequal geary su**ces with different angle to the axis of rotation and different number of teeth. But finally I found a solution and it turned out good, so here is it.

As follows from the name, it is a Pyraminx with geared elements. When you turn a corner, the adjacent edges move and rotate at the same time. After the edges shift by 120°, you can turn another corner.

The edge gears have 6 teeth, the corners have 9 teeth and the su**ce upon which the edges are rolling, has 15 teeth. Before the puzzle was stickered I found that it's not a simple task to put all gears into correct orientation. With the stickers, I could not solve it yet.
