Shower Foot Soap Stand

I remember long ago, when I use to visit my grandmother, she would have a machine that my brothers and I would love to play with. It had a big chrome middle part (where the engine was) and a fluffy blue cone on the left and a fluffy red cone on the right. It almost looked like a "T" with the arms being the cones. With a flip of the switch in the middle of the chrome the fluffy cones on either side would start spinning incredibly fast. Then, one would put their shoes against the spinning cones and buff them to a shining perfection. We, being the boys we were, would try to buff G.I. Joe's face off...

Now, back to the idea... Have a wooden stand akin to the one mentioned above but with no motor. Instead of fluffy cones, have cones of soap. And since there is no motor to buff the feet up there needs to be little scrubbing beads (or I've even seen seeds and sand put in it) on the top and points of the cones so the calloused parts of the feet can get the proper scrubbing they need. The bottom of the cones should be smooth so as to not irritate the skin on the top of the feet.

Replacement soap is a must. There can be different colored soaps and different 'flavors' of soap. Spring Rain, Autumn Mist (or 'Myst' so as to make a few extra $'s), and rose petals, etc etc. The insert the soap would go on would have to be beveled in such a way that the scrubby part would always fit on top and not move in the middle of a foot scrubbing. Also, the base would either have to be weighted, suctioned, or bolted down so the unit wouldn't move in the midst of a vigorous scrubbing.
