Bitfall, rain-printing machine by Julius Popp

Take a look at this documentary film about a rain-printing machine developed by artist Julius Popp named Bitfall. It is amazing how he produced this! Below is a small diagram of his piece. You can check out Julius and his work at Spherical Robots.

Infosetchics had this to say about this piece:
Bitfall is “a physical water sculpture with 128 synchronized magnetic valves, so that a wall of falling water drops can be perceived as a graphical bitmap matrix. A computer application selects currently popular keywords from news websites, & displays them on the transparent ‘information curtain’. the ‘information flow’ metaphor literally demonstrates the dynamic & ever-changing character of continuous information streams from which users build their associated experiences.”
