The QiYi Hexagonal Klotski may be the first of its kind, while many computer nerds have created simulators for it, I am not aware of the physical thing having been released before, instead of squares like a normal klotski, this has triangles and they move around a hexagon shape too, it is not much more difficult than any normal klotski puzzle but it may still interest some people and therefore I have it available.

You can buy it here
