399 moments of zen
It's like printing...with water...in midair.
As I said to someoneElse, "Japan gets all the cool sh*t." He corrected me, "Japan MAKES all the cool sh*t." (Though in this case, it's German artist Julius Popp.)
In either case, this is one of the best things I have seen in a while. Relaxing. Great use of technology. Enjoy!
