We can't stop watching this speaker wobble

No, really. We can't look away.

The animation above was taken from the video featured below, which appears to shows speaker cone undulating in hypnotizing slow-mo. It was created by photographer drummaboy5189, by playing a 61Hz tone through the speaker and filming it at 60 frames per second and 1/4000s shutter speed on his DSLR. The slight off-set between the speaker's motion and the camera's framerate gives rise to a mesmerizing rolling shutter effect.

We've seen a similar effect achieved with water – but the slow-motion illusion seen here is just delightfully weird and otherworldly.
