Pointer & Yenathi

Hey Pointer, I’ve been dreaming about a fabric that changes color with every step you take – think of a simple algorithm that reacts to movement. What do you think?

Sounds like a sensor‑driven pixel array. You’d need an event loop that maps displacement vectors to hue offsets, then a lookup to drive the pigments. It’s basically a state machine—just make sure the update rate outpaces the stride speed. Problem solved.

Wow, that’s a neat tech spin! I can already picture the runway—each step a fresh hue. But what if we sync it to music too? Also, we need a fast microcontroller; I don’t want the light lagging behind. Let’s prototype ASAP.

Syncing to audio is just another event source – read the beat, map tempo to color transitions, merge with the motion stream. For a microcontroller I’d pick a Cortex‑M4 with DMA and a fast timer, maybe a Teensy 4.0, so you get sub‑millisecond latency. Let’s sketch the state machine first, then wire the accelerometer and an audio ADC. Prototype in a week, we’ll see how the colors dance.
