I love my Desktop Rain Machine here on my desk at Green Head HQ, but I really think I need to go larger, much larger. Without literally having to harness a real rainstorm, I found the next best thing, the Ultimate Rainfall Fountain ($900). From a light mist and small sprinkle to a complete storming downpour, the giant 7 foot tall Rainfall Fountain continuously recirculates 8 gallons of water into a beautiful show of showering art and sound.
