Watching a film or listening to music in a dark room with plain static bias lighting always feels like a missed chance to me, so this test caught my attention. The maker is working on an app that drives a home lighting setup in sync with sound, and this is another round of testing it in a real living room rather than on a bench.
The arrangement is well thought out. LED strips sit behind the wall-mounted television and run along the upper ceiling molding, and a spherical paper lantern pendant plus a table lamp with a rectangular shade join in as light sources. The room itself reads as a proper listening space, with a stereo console carrying an amplifier, turntable and speakers, and a framed JOY DIVISION poster on the wall beside the TV. Everything pulses, dims and shifts in tempo with the audio, here an electronic rock track with heavy beats, synthesizers and female vocals. The palette mostly moves between deep red, amber and near darkness, and at one point a brief burst of bright cyan-white fills the room before sinking back to black. Toning the settings down compared with earlier tests seems like a sensible call for a space you actually sit in.
One thing stands out as an open question: the controller hardware is not visible anywhere, so the microcontrollers, LED drivers or software controllers behind the patterns remain a mystery. I would love a look at that side of the build. The maker has also mentioned a flicker mode, which sounds like a fun addition to the reactive behavior already on display.
