I wanted something that’s genuinely relaxing to watch and listen to, but still visually “sticky” enough for longform videos and Shorts. So I built a generative visual instrument in Python. This program simulates drifting fireflies inside an aurora-like flow field. When they cross invisible curved “strings,” they trigger soft bell tones in a musical scale. The visuals respond gently to the music with glow, trails, and slow mood shifts, with no flashing or harsh effects. Built with Python, Pygame, and NumPy. If you want more of these “visual music” experiments, subscribe. I’m building a whole series of soothing, weird little instruments.
