hologram
Feeling jealous of Tony Stark’s Jarvis? Soon, you may have a hologram assistant of your own!
For as long as we can remember, holograms have been one of the coolest science fiction technologies that still haven’t quite lived up to the promises of our favorite films and TV shows. We’re a long way from chatting with Mark Twain on the holodeck, basically, but that doesn’t mean current “hologram” technology isn’t cool!
One of the neater everyday hologram-like technologies you can easily buy is a propeller clock. In fact, using a simple microcontroller, some LEDs, and a spinning motor, you could even build your own propeller clock. But this enterprising Twitter user decided a propeller clock wasn’t enough and ended up making a propeller watch! It’s not entirely practical, but it is completely awesome!
