This is Uwe Meffert. He was the first one to invent a 3-dimentional rotating puzzle. the Pyraminx puzzle. This was a couple of years before Rubik's cube. Too bad it wasn't a commercial success before the cube. If so,  Uwe Meffert would be the most well known puzzle inventor of all times. But hey, what the heck, look at him smiling. He sure is a worthy runner up.  

This is Meffert's Pyraminx puzzle. It's a 3-dimesional rotating puzzle in the shape of a pyramid. Thru the years, a couple of different types have been produced. there are white and black pieces. And all kinds of different colored stickers. What more is their to say, than it turns very smooth, and the stickers won't come off. 

Well, this is all for know. Maybe I will add a couple more puzzles soon.
