You are at a public plaza and notice a new interactive water fountain installation that responds to people's movements in an unusual way.

The installation is attracting a lot of attention, and you think your friend Jake, who is studying interactive design, would be interested in seeing it.

Call Jake and describe in detail how this unique water feature works and what makes it special.

Explain what happens when people interact with it, and ask if he would like to come see it in person.
