Michael Huggins and I recently completed an installation at zero station in Portland, ME. It will be up all month, although scaled-back. Here are some photos and video of the work in its full form:

The wall text reads:

The two artists have filled the gallery with Japanese Knotweed, a fast growing invasive weed harvested from the surrounding area. The plants, together with visitors’ bodies, modulate a complex sound installation as electric signals connect the plants, humans, and electronics. Did you know that plants communicate with each other using sound waves? Come in and talk to to some plants that are taking over the northeast.

To modulate the soundscape, gently grasp a plant’s stalk and hold on!

And for the geeks: we wired the plants to work as capacitive sensors using two Arduinos which talked to a PureData patch running in Debian Linux.
