Inventors Windell Oskay and Lenore Edman demonstrate the CandyFab 4000, a printer that creates 3D sculpture by stacking 2D images made of sugar. Drawing from disciplines as varied as circuit hacking and sewing, the sugar printer is only one of Oskay and Edman's many projects, which include an interactive dining table and hard-drive wind chimes.

Tinkerer, programmer, and musician Ken Murphy shows how to build electromechanical "bugs" built from scavenged materials and powered with a single coin-cell battery. When the Blinkybug's wire antennae detect motion from air currents or vibrations, the bug comes to life, with its LED eyes blinking in rhythmic patterns.
