Helen Evan & Heiko Hansen have created a wall virtual bricks, where every brick is a pixel. They site describes it best: "screen as architecture: every brick as a pixel, architectural form for self portrait"
Implications - The idea of virtual images is no longer just confined to the computer screen. The advancement of technology has allowed for high resolution imagery to be projected onto walls and to take it one step further, most have interactive capabilities. Musicians such as Nine Inch Nails have used this for visual purposes before. How tech companies will translate this type of technology for more of a practical use in the home outside of entertainment will be interesting.
