I’m back on crazy hardware hacks this week. Check out this insane Volumetric Display using an Acoustically Trapped Particle. It uses ultrasonic waves to levitate and move a tiny foam ball to create images. They even use color LEDs to apply color! The video gets pretty technical, but you can ignore all that if you want and just look at the thing in action. Nuts!
It's a butterfly!
Very Bad Wizards did an episode on Severance this week with psychologist Paul Bloom. (Warning: Spoilers galore in the podcast. Finish the show first.) I enjoyed their take on it as a work of philosophy. Are innies and outies the same person if they don’t share memories? What’s the difference between past us making binding commitments on future us and outies making commitments on innies? Is it possible that anesthesia is morally wrong, depending on what’s actually happening in the brain during a procedure?
