The Saturn Nextfest Grass Wall, created in 2006, was a 45-foot wide video projection of an animated field of grass. What made it exciting is that each blade of grass moved independently and would move more quickly as spectators moved in front of it, implying that the visitor was created a small breeze that was impacting the grass. The audience was also able to input messages on a kiosk and have those displayed in front of the grass for short periods of time.This project is one of the first that convinced me of the power of reactive spaces. It was produced by big agencies shown at a big event and was beautiful, engaging and impactful. At the time, it was also one of the best examples of the then-in-beta, now released, Processing programming language.
Reactive walls are still underleveraged as tools to express attributes of a brand. They are relatively inexpensive to create and maintain and can be used to tell great stories and get customers to interact with a space very easily.
