Concept Summary: Quantum Dots, nanoscale sandwiches of semiconductor that hold a standing wave, can theoretically be made to display atom-like behavior. Which atoms? Vary the voltage. Thus, matter can be programmed to display the properties of many different materials at the flip of a switch. Make a thread of quantom dots, weave millions of them together, and you have what they call Wellstone - a programmable block of material. There are limitations, yes, impracticalities galore, but programmable matter holds promises hidden and obvious that just might change the world.

Programmable Matter Thanks to http://ellipsis42.stumbleupon.com/ for this great link. Let me quote from his summary since I can do no better:
    "Concept Summary: Quantum Dots, nanoscale sandwiches of semiconductor that hold a standing wave, can theoretically be made to display atom-like behavior. Which atoms? Vary the voltage.

Learn More The best online reference for lay readers is "Ultimate Alchemy," a 7,000-word article from WIRED magazine available (minus the pictures) at: http://www.wired.com/wired/archive/9.10/atoms.html. Offline lay-references include Richard Turton's THE QUANTUM DOT: A Journey into the Future of Microelectronics (Oxford University Press, 1996, ISBN 0-195-10959-7). http://www.amazon.com/exec/obidos/tg/detail/-/0195109597. an d Wil McCarthy's HACKING MATTER: Levitating Chairs, Quantum Mirages, and the Infinite Weirdness of Programmable Atoms (Basic Books, 2003, ISBN 0-465-04429-8). http://www.amazon.com/exec/obidos/tg/detail/-/046504428X. Fo r serious theoreticians, Paul Harrison's Quantum Wells, Wires, and Dots (Wiley, 2000, ISBN 0-471-98495-7) provides equations and computer code for estimating the behavior of confined electrons. --------------------- Another approach to programmable matter A "Claytronic atom", or "catom", is a nano-scale object, covered with electromagnets capable of attaching the catom to other catoms. LEDs, and photo-sensors on the surface complete the picture (no pun intended). A suitably programmed ensemble of catoms could dynamically replicate just about any object - even a person. Some have called it "dynamic physical rendering". Whatever you call it, the technology is probably a decade off (famous last words). Carnegie Mellon University researchers Seth Goldstein and Todd Mowry lead the small, DARPA and industry-backed research team that is investigating the engineering of these devices.
