The magic bench(es) is/are located in an overlooked hallway in the ITP floor.
They shine with joy when they perceive movement; they might be inviting people to sit on them or they might be encouraging them to keep moving.
They go from a saturated and not-so-bright deep red color, to a warm and bright yellow. They took the inspiration for their hues from looking at nascent fire and several sunrises – and dying fire and several sunsets.
Their “brain” uses GNU/Linux running Processing and Q Light Controller +. Their “organs” consist in two webcams, four ColorKinetics ColorBlasts, one PDS-150e to controll them, and one Enttec Open DMX-USB interface.
They use the two webcams to look for changes in a total of four different sections or points of view – each webcam feed is divided in half. The amount of change in each of the sections triggers a proportional change in the light characteristics in each of the lamps. Linear interpolation is used to ease the transitions.
The files used are in this Github repo:
Here‘s a post that documents how I connected the two programs.
