The Data Fountain is an ambient display that translates streaming currency rates to streams of water. From Koert van Mensvoort's description of the project:
"In the morning paper, I can read the weather report as well as the stock quotes. But when I look out of my window I only get a weather update and no stock exchange info. Could someone please fix this bug in my environmental system? Thanks."
Of course, the Data Fountain comes six years after pervasive computing pioneer Roy Want built a fountain at Xerox PARC that trickled or gushed based on the company's stock price. (Thanks, Alex!)
