Audio Signals of a Prickly Pear Cactus (Opuntia)

Discovered and filmed at the Royal Botanical Garden in Edinburgh, Scotland.
One of the personal highlights when I went there.
The sign on the pedestal says:
"Opuntia by Lucas Abela
This Opuntia is creating the audio through biofeedback.
The inherent electrical activity within the plant is converted into musical signals which the plant uses to control modular synthesis."
Unfortunately I couldn't get any silent moment in the room when there would be no talking in the background, hopefully you still can hear the amazing sounds.

So hört sich mein Magen auch an, wenn da gähnende Leere drin ist. 😉
