Matty Sallin, a former Interaction Design Ivrea student, and Greg Trefry have made a lamp that helps you visualize your pulse:
An ornamental lamp that detects and "echos" your own heartbeat in realtime. Just place your hands on either side of the lamp base and wait 6~10 seconds for it to detect your pulse, then watch as it throbs to match your heartbeat.
A nice visual design. I find it strangely reminiscent of the judge character from Pink Floyd's The Wall or a nun's hat thing, but that's just me and it is heart-shaped, which is what I think they were going for.
Lighting seems to be a common entrypoint into the augmented furniture world right now, which makes sense: there's nothing that has to move, it IS ambient display, and it's been established (by Ingo Maurer in high design, and Pottery Barn for a more traditional audience) that it can come in many forms and still be acceptable to a large audience (not so with the sofa, for example).
