When I worked in Switzerland, a few places boasted 'Closomat' toilets. They had two elbow-operated levers mounted on the flush box.
Once you had dropped your load, the first lever sent a jet of warm water straight at your bum hole, followed by a blast of warm air to dry everything off.
I just loved the Japanese toilets, heated seats, auto open and close both lids, temp control on the water, his and hers washes, auto flush when weight is of the seat and even music on some. Really not much else to do except sit down and then stand up.
