So you might remember the guys from OK Go from their HUGE viral music video from 5 years ago where they danced on treadmills.

Well, they continued making really cool music videos, like they one they put out today for their song "The Writings On The Wall." Nearly everything in this video is an optical illusion, and it's probably gonna throw your brain for a loop in a couple spots.

Can you imagine how much time it took to set all of this up? Wow.

 

 

And here's their classic treadmill video for "Here It Goes Again," just in case you haven't seen it, or want to watch it again. It's still really fun!
