Math + 80s glamrock = Angle Dance. The rock group “Plane Geometry” singsplains angles in this clip from Children’s Television Workshop’s Square One Television, a show dedicated to teaching math. It ran from 1987 to 1992 (if that timeframe wasn’t already very, very clear from the video).

There’s more math in the archives. 

Thanks, Leigh.

Even if you’ve seen This Too Shall Pass, the 2010 instant classic from inventive band Ok Go, it’s a great video to watch again (and again).

With the help of SyynLabs, director James Frost, and the support of almost 60 people (from core builders to people helping to reset machines) OK Go put together a massive Rube Goldberg setup that includes bowling balls, barrels, sledgehammers, umbrellas, legos, a car, an unfortunate piano, and paint cannons.

This Too Shall Pass also has an “official” video:

And of course, it’s fun to watch these related OK Go viral hits again, too: their breakout single Here It Goes Again, and Three Primary Colors for Sesame Street.

More Rube Goldberg machines are in the archives.

Toast slices as dominoes? Yes, please. This domino-driven Rube Goldberg-esque video may not be all in one shot — and maybe some of it is helped with some digital post-production? I’m looking at you, parachutes — but the use of a fan with feathers, a flip-book style animation, an underwater shot, and a few Cobra Weave Exploding Stick Bombs all throughout a huge house sets this one apart.

A-Trak & Tommy Trash’s Tuna Melt, directed by Ryan Staake. There’s also a behind the scenes vid.

More Rube Goldberg and chain reaction videos await in the archives.

Has the kid seen this 1977 Sesame Street classic? Pinball Countdown, featuring the Pointer Sisters.

Inspired by Joey Ramone’s posthumous love letter to New York City, directed by Greg Jardin, high school student Kevin Chiu spent two months taking 1991 photos of 140 Hunter College HS peers and teachers to create his own stop-motion homage.

More (The Hunter Pixilation Project) is scored to the song Leaves by Cheers Elephant.

Enjoy the video inspiration, too:

Thanks, Kevin.
