Ploopy Bean: a trackpoint for every computer

Isn't the point that it's integrated in the keyboard, so that you don't have to move your hands away to use it?

I'm on the lookout for a wireless ball mouse. I want to relive the glory days of cleaning out the little cylinders on the inside of the mouse without being constrained by wires.

Might be possible to embed one of these blackberry cellphone OEM trackpad inside a keycap https://www.ebay.com/itm/132886140650

This gives me an idea, does anyone sell these?:

    HEU   N
    DIN    U

This is made for me.
