Maybe Tiny Fidget Cubes?

I don't know I just made that up. Tiny Fidget Cubes would probably be great in my opinion. If anybody works at Tiny Circuits, I think this is probably the best idea for some people.

I'm not smart, This is just a suggestion.

You could use this idea or not, it's your choice
