Steve Mann, Chris Aimone, et al of the University of Toronto have developed a system for using streams of water to play a musical instrument. They describe the results in theoretical terms for the academic community, referring to ancient Greek water organs and the ability to have greater tactile feedback than other alternative instruments. But let’s get to the bottom line: this is a fun water toy that is not only tactile, but wet. You can play the instrument by manipulating streams of water directly:

The “FUNtain” (hydraulophone) is an interactive multimedia fountain that responds when people block, one or more of the water jets, or touch, restrict, or interact with the jets. In particular, it can function as an extremely expressive musical instrument in which each jet of the fountain is a soft key that can be pressed in infinitely many ways to obtain fine control of note volume, pitch, and timbre.

I find that people overuse the term “infinitely”, but it does look like an expressive and open-ended instrument, not to mention one that’s going to be fun to play on a summer day. (And ironically, they introduce it in Canada, not Florida.) The good news: they’re going beyond their earlier, simpler water fountains, which produce sound acoustically, to outfit their water instruments with a MIDI interface. That’ll make this the world’s wettest MIDI controller.

Keyboards made from rows of water jets, sprays, and nozzles as direct user-interfaces to water-based, fountain-based, and underwater musical instruments [Paper; that’s the actual title, not an abstract, though it could be an abstract!]

FUNtains, with gallery, which include more acoustic instruments as well as these digital interfaces

For a somewhat less-direct water interface (using camera and sound tracking of water), see the MOcean project, which was just shown here in New York.

Thanks to Matt Fellers for this one, who sums it up neatly: “Crazy Canadians…”

  • For anyone in Toronto (Ontario, Canada), one of these FUNtains is being introduced at the Ontario Science Centre:

    There is also a video here.

    I will tell you what I think later on this Summer when I get a member's preview of the exploration plaza (if anyone cares!).

  • That's great, Daniel. I care, at least. 😉

    If you get any photos, etc., let us know — not only for this site, but for Create Digital Motion, as well.

    Now I have to get up to Toronto; this stuff looks great.

  • Truly useless.

  • That video is a trip. Now I can play while swiming around. : ) The eyes! ; )

  • Where's the video? Where's the audio?

  • There is a video here, as Daniel O pointed out; it's in the margin:

    … and if you click on the speaker just below it, you'll get sound. (Loud; be careful!)

    I also see some videos here, in other formats:

    The websites are extremely hard to navigate, sorry. I guess they were busy building the things and teaching. Or the part of your brain that lets you do engineering is separate from the bit that lets you do web design. 😉

  • I don't need no midi controller!!!!!

  • Someone was walking past the hydraulophone and started playing some Bach on it. There is an inline video in and some pictures in

  • You can see and hear another version of the hydraulophone:

  • Building on the physics-based organology of which the hydraulophone is a part of, I have been contemplating the "oneirophone" as a new musical instrument classification for this system. In this particular instance, I define oneirophones as musical instruments in REM dreams. Oneirophonics are sounds as experienced in those dreams. Oneirophones could fall under the quintephone category, but at the same time encompass all musical instruments since anything can be in a dream…

    Perhaps another sub-category could be introduced for musical instruments in daydreams, waking memories, nostalgia and futuristic visions as well, since "sound" in daydreams sounds and is experienced differently to those in REM dreams.
