Condensate pipes as water features

Point of architecture: I can't believe I missed this before - air conditioner condensate pipes are modern water features; this is an underutilised idiom. | Air conditioners suck water out of air and put the condensate somewhere; they are effectively water pumps - which pump at a rate which varies based on the condition of the environment. It's quite pretty once you figure out what the design possibilities are for this - for simplest example, an aural tempo is established by the rate of dripping, which informs occupants about the state of water in the system.
