I saw The Wizard when I was 10. It was a pretty shit film but it previewed two things : Super Mario Bros 3 and the infamous Nintendo Power Glove, the peripheral that every gamer wanted but very few actually had.
Matt Mechtley from biphenyl.org is also a fan and for the 20th anniversary he decided to design a new version of it. He replaced the ultrasonic sensors with an accelerometer, the proprietary microcontroller with an open-source Arduino, and the wired connection with Bluetooth (his words, not mine!).
In the video below Matt shows you how he improved it. It goes a bit too techy but I'm sure those who love retro gaming will enjoy it :)
