LEGOs have been used to make many things – homages to geek culture, cities and now, a fully functional mechanical clock. Made by Hans Anderson, the Time Twister clock looks simple but is incredibly complex. Powered by two LEGO Mindstorms NXT micro-computers chatting over Bluetooth, the Time Twister tells time in a completely awesome and hypnotic way, while noisily telling you that yes, it’s now 10:00 and you’re already late for your appointment. Mr. Anderson managed this impressive feat of nerdery by making the two LEGO Mindstorms bricks communicate via Bluetooth. Seriously, pictures won’t do this thing any justice, it’s best if you just watch the video of it in action:
