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.

From early 2010 in Paris, Matt W. Moore paints a mural across the street from his SINCE Gallery “Crystals & Lasers” exhibition.

Entomologist Dr. Jürgen Otto films the Peacock Spiders of Australia, and they are super fun to watch. Though they are not well documented, there are 20 known species of these small jumping spiders. They have huge eyes, grow to about 5mm, and the males have colorful iridescent flaps that they use to attract females.  

GrrlScientist has written more about Dr. Otto and these unique little creatures, and you can see more photos (and an interview) on 1000 Natural Wonders.

From the 2012 Concurs de Castells, a human tower-building competition in Tarragona, Spain, watch this video by photographer David Oliete. David also took photos.

A long tradition in the region, castells began at the end of the 18th century. The sport has rules, techniques, and team responsibilities to guard safety and success. The pinya or base is made of a few hundred people that can catch anyone who falls, and the tower itself has a variety of different formations. The top three levels are the pom de dalt, made up of children in helmets. 

While the video above doesn’t show some of the more harrowing challenges, this video by Mike Randolph in 2010 captures why safety and teamwork are so important:
