Here's the Slo Mo Guys teardown. Very impressive tech.

What was fun for me was the fact that when this thing came out everybody I knew thought it worked by shooting red lasers at your eyes. There was very little internet to use to look it up either so I was shocked when this video showed how it really worked.
I think that was the video!
Was a random YT recommendation, so I didn't know the source off the top of my head.
Wow, that was awesome. They had to crank up the FPS of the high-speed camera into the millions of FPS to see that brightness control over every individual LED was done by flashing it multiple times per scanline. Very cool.
