Taps 16: the wings

This one is nice. It is only possible to pull the handles towards yourself. No confusions on how to operate it.

I found another one of these

Taps 15: joystick to play with

Another funny one. There was no hot water and the stick could be moved in all directions. The flow was controlled by the distance of the stick from the centre. There's no way to keep the water flowing without holding the stick?!? Maybe the designer(s) thought of the way to save the water, but it's useless. One can only wash one hand at the time.

Taps 14: a push me tap

This one needs instructions as well :). I first waved at it (I expected something similar to this tap) and then read that I need to push the button on the top.
