I've been researching kinetic structures and mechanisms lately and I stumbled upon the above video of Kerry Jia Yi Lin's kinetic dress. I had seen this project before but never in live action. It's great to see the garment's movement in relation to the human body.
The garment essentially is a barometer for the wearer's stress levels. It uses a heart rate sensor to trigger movement of the dress.
The project is wonderfully documented at Lin's site so please check it out for more detail.
