I've been working with Daniel Fishkin on a electronic sound art project called The Lady's Harp. It's a large scale installation that uses acoustic feedback (from guitar pickups) looped back through contact transducers, which induce vibration on piano strings. Daniel has installed this instrument in a few other settings, but needs it to be easier to set up & tear down, so I'm helping with some basic mechanical design. We're using mostly off-the-shelf components - primarily 8020 extrusion - and a few laser cut acrylic parts.

We're mocking the components up in the next few days, and Daniel will be installing the Lady's Harp in Nothing Space later this month. I'll have more updates soon, but Daniel's description of the project is much more elegant and informative :)
