If you’ve ever read William Gibson’s novel “Virtual Light” you know what augmented reality is. (If you haven’t read it, you should stop looking at this and go buy it right now.) Layering virtual objects on top of the real world is the name of the game, and now you can play it at home with the help of ARTag.net. Try not to be discouraged by the Bob the Builder aesthetic.

Two Ph.D. candidates at MIT have invented The Sound of Touch, a digital instrument that texturizes sound. It works like this: you use a microphone built in to the wand-like instrument to record a sound, then you brush the tip of the wand across a surface. A processor translates the shape of that surface into an effect applied to the sound. Sandpaper would gives your sample a gritty sound, silk a satiny smoothness.
