hole in wall

"Dr. Mitra heads research and development at NIIT, a leading computer software and training company in New Delhi. Just outside his office is a wall that separates his air-conditioned 21st-century office from a slum. Mitra decided to place a high-speed computer in the wall, connect it to the Internet, and watch who, if anyone, might use it. To his delight, curious children were immediately attracted to the strange new machine. "When they said, 'Can we touch it?'" Mitra recalls, "I said, 'It's on your side of the wall.' The rules say whatever is on their side, they can touch, so they touched it."" via frontline/world Rory O'Connor
