⚡️👀 FUN FACT - An internet user turned a simple Walmart supermarket price tag into a mini-screen displaying the Bitcoin price, using the artificial intelligence system Claude. These small tags, normally used to display product prices, feature an e-ink screen. By reprogramming them, it becomes possible to display financial charts, images, or other customized information. The most interesting part is that these screens consume very little energy and retain their display even without a continuous power supply.
