How a lead-acid battery works

“Kinetic Rain” Singapore Airport





In the course of refurbishment works ART+COM was commissioned to create a signature art installation for the Departure-Check-in hall of Terminal 1 at Singapore Airport. “Kinetic Rain” is composed of two parts, each consisting of 608 rain droplets made of lightweight aluminum covered with copper. Suspended from thin steel ropes above the two opposing escalators, each droplet is moved precisely and seemingly floating by a computer-controlled motor hidden in the halls ceiling. The drops follow a 15-minute, computationally designed choreography where the two parts move together in unison, sometimes mirroring, sometimes complementing, and sometimes responding to each other. changiairport.com

One Hundred and Eight




One Hundred and Eight is an interactive wall-mounted Installation mainly made out of ordinary garbage bags. Controlled by a microcontroller each of them is selectively inflated and deflated in turn by two cooling fans.
Although each plastic bag is mounted stationary the sequences of inflation and deflation create the impression of lively and moving creatures which waft slowly around like a shoal. But as soon a viewer comes close it instantly reacts by drawing back and tentatively following the movements of the observer. As long as he remains in a certain area in front of the installation it dynamically reacts to the viewers motion. As soon it does no longer detect someone close it reorganizes itself after a while and gently restarts wobbling around.
