How it Works
We first had to think about how to hold up our panels. Our biggest issue was finding a way hover panels over the staircase, since the tall ceiling height meant that no one could reach the ceiling while standing, and no one could reach far enough over the staircase to place our panels where we needed them, even while standing on a ladder. Our solution, after thinking of a series of failed ideas, ended up being a lightweight metal frame with cross bracing spaced at the intervals we wanted our panels to hang from. The frame itself was about 20 feet long and 10 feet wide, allowing it to hover over a satisfactory amount of the space's floor area, meaning that we could spread our panels through the entire space. We secured this frame at its four corners by drilling into the left and right (long) walls of the space. First it was constructed on the ground with the studs vertical and then flipped horizontally to rest on the stairwell railings, and finally, lifted up to a little over 10'.
Unistrut channels, generous duct tape, and non-invasive mounting arms were used to hold up the lights around the perimeter of the room. The most challenging part wasn't wrapping the materials carefully around the PVC frames but rather, figuring out how to cut the fishing line to angle the pieces as intentionally as possible. We used silver carabiner clips to attach the 4 individual strands of fishing line coming from each of the four corners to anchor into a 5/16" hole in the metal framing.
We then worked with the DMX lights themselves, continuing to tweak our reflections and diffusions in order to light up the entire space while still ensuring that spots of interest were created to break down the space. These spots ended up being the focus of most photoshoots in the stairwell.
A webcam which was mounted at the back wall, above the black couch, tracked blob movement near the top of the stairwell. With increased detected activity, TouchDesigner would trigger the lighting to grow increasingly magenta and with the most blob movements, changed to red. With no detected movement the environment was rendered to a blue-indigo.
We experimented with various color slider speeds, and found that a faster change rate allowed for people walking through the space to immediately notice the change in color, and look up as they walk down. This created a connection between the space and the people moving through it, encouraging people to stop and pay attention, and inviting people to play with the light changes.
