The two Daniels built a hardware interface to receive millivolt signals from plants and sonify them in MAX/MSP on an Apple MacBook Pro. Their results and especially the reactions of the plants were eerily similar to our own findings. Most interesting is the end of their video, seen here, where the plant reacts to the intent to close their program, but stops when they point this out.
Their project was inspired by many of the same researchers that we have looked to: Cleve Backster, George L. Lawrence, and Michael Theroux.
