I understand that we wash our hands more often than we shave. And a sink works well as an elliptic horizontal to us, so both hands fit well in there at once.
But it sure isn’t shaped right for rinsing your face.
Business idea: rotating sink. Hit a switch, the elliptic pivots to give you a nice face-rinsing shape; water doesn’t go all over the floor.
Maybe I’ll pitch that to Kramerica.
