The world would be a better place with more bubbles around. And as noise-y as we are, this would be the perfect trigger for the cuteness that could ensue.
The people at littleBits had an ITP Camp session, which ended up producing this incredible sound-triggered bubble maker. The gadget itself is not that complicated; its creators, Toshitaka Amaoka and Chris Mansfield, made it using a fan, a 9 volt battery, wood, a plastic cup, and a sound trigger module from littleBits. See it working in the video below.
