For Those Who See is a 2010 installation by Berlin-based artist Daniel Schulze that relies on a 7×7 grid of audio speakers to generate rings of fog that shoot upward from the device. The vortices appear for only a second or so, but are distinct enough that Schulze could then translate digital signals into fleeting visual patterns. The installation was a jury recommended work at the 14th Japan Media Arts Festival and won the audience award at the Create10 Student Design Competition.
