What resulted is a “rolling speaker” effect.
Here’s a photograph showing the simple setup that was used:

We’ve featured a number of strange effects caused by cameras’ rolling shutters in the past. These include guitar and bass strings turned into jelly, water frozen in midair and floating upwards, and a helicopter that appears to float with motionless blades.
