Check out this work from Mike Olbinski:

He writes,

It took four years but I finally got it.
A rotating supercell. And not just a rotating supercell, but one with insane structure and amazing movement.
I’ve been visiting the Central Plains since 2010. Usually it’s just for a day, or three, or two…but it took until the fourth attempt to actually find what I’d been looking for. And boy did we find it. […]
We chased this storm from the wrong side (north) and it took us going through hail and torrential rains to burst through on the south side. And when we did…this monster cloud was hanging over Texas and rotating like something out of Close Encounters.
The timelapse was shot on a Canon 5D Mark II with a Rokinon 14mm 2.8 lens. It’s broken up into four parts.
