So many interactive works are using signals coming from inside as meaningful/meaningless source of image and sound effects. Let’s try another collective experience!
People are seated in a circle around a big subwoofer speaker a finger plugged into a heart beat detector. The combined rhythms of the seven participants should, when synchronised, make the light ball float in the middle of the middle space with the pressure of air propelled by the speaker. Amazing how we can, more or less consciously, drive our inside body.
