Instead of imagining future cities dominated by stalker-esque interactive advertisements blaring from every corner a la Minority Report, imagine if cities formed artistically symbiotic relationships with their human populace. That is the vision proffered by design group Urban Alliance from the Netherlands, the creators of the Moodwall.

The group created a series of motion sensitive interactive walls that respond to the movements of pedestrians walking under deserted, and sometimes dangerous, underpasses. The patterns, powered by 2,500 LED lights and a video system, are designed to give pedestrians a feeling of security, but as the technology develops these kinds of walls will probably begin to give humans the sense of a real, living city communicating in digitally organic sign language. Creepy, yet cool.
