"In the park next to my home there is a fountain. I can see it from my studio window. Day in day out it sprays its water in the same boring fashion - no information in there. I connected this fountain to the cell phone of my secret love. The fountain now sprays high when she's in the neighborhood and low when she's away. It sprays wild when she is receiving many phone calls, and not spraying at all when her phone is off.
People think it's a randomly programmed fountain. But they are not into ambient information like I am."
... and some other examples.
