Hansgrohe Touch Screen Shower Rainbrain
RainBrain by Hansgrohe is an electronic touchscreen panel with five individual functions. It works much like a touch screen iPad. The system allows for 4 preset functions that controls the flow of water to the rainhead, shower arm, and the jets. Differing sprays and water flow from the rainhead are available.
There are some features uncommon to most showers including a warm-up function that flushes out cold water and automatically adjusts to the present temperature as soon as it is turned on, as well as water cascade, hot/cold shower alternation and music selection from a Bluetooth.
Hansgrohe has a really cool simulator, which shows the various functions of the shower unit first hand. Link is below.
