Driven by 3D-printed fluid logic circuits, custom silicone membranes, and vacuum pressure, this soft display doesn't just render images… it's a physical, tactile screen that might actually be a soft robot in disguise. By combining row-and-column pneumatic multiplexing with built-in memory cells, the matrix "writes" data line-by-line and latches pixels in place without continuous power. Scaling up from 16 to 64 pixels forced me down a deep micro-scale engineering rabbit hole, but the result is a living, breathing matrix that brings digital pixels into the physical world. 🛠️ Timestamps: 0:00 – Circuits running on Air? 2:50 – The Vision: 64 Pixels 4:18 – Memory Screen? 7:00 – Hardware Upgrades 9:28 – Scaling up! 12:08 – Rainbows & Warping 14:35 – It’s Alive! 📚 References: [1] Jensen, E.
