Molten metal, paragliding, and a DJ who doesn't just press play.

• In February, Bad Bunny's Superbowl Halftime show was watched live by more than a hundred million people, and it has as many views on YouTube. It was almost entirely performed in Spanish: so for those wanting more context, this unofficial English translation and commentary is so good. Because Sadja hasn't just translated the performance: she's reshot and re-performed parts of it, as a split-screen with the original. She's improvised costumes and green-screens, and used her friends and family as background performers. And if that wasn't enough: there's additional "pop-up video" facts that fill in additional context. This is fascinating, exactly the sort of thing that YouTube was meant to be for, and it let me see the original performance in a whole new light. (Thanks to Greg for the suggestion!)
   
• There are many, many, many, many, many long-form slow-TV videos from the cabs of trains. But this, from Cabview Holland, is unique: every thirty seconds or so, the seasons shift. The footage is matched with painstaking precision, day to night, winter to summer. It's technically very impressive... but also sits in a weird middle, where it's not quite interesting enough to constantly pay attention too, but too interesting to just put on in the background! (Thanks to Jason for sending this over.)
   
• Having only just learned their parts, 2,500 strangers in Montréal sing Leonard Cohen's Hallelujah. Originally, I thought this might be an "and finally" link for the end of the newsletter, but no, this absolutely deserves a place in the main section. (Thanks for suggesting this, Manuel.)
   

• Why so many control rooms were painted seafoam green.
   
• Automating those "hey, want to feel old" facts has been on my ideas board for so long, and now I don't have to, because someone has automated those "hey, want to feel old" facts. Actually one of the most downbeat things I've linked to in the newsletter in a long time, turns out I'm glad I didn't make it myself!
   
• And on a much brighter note thanks to reader Christopher for reminding me of Geograph, a web project that was started more than 20 years ago to take a photo of every 1km grid square in Britain and Ireland, all 300,000+ of them. The resulting photos, more than eight million of them, are Creative Commons-licensed and have formed an incredible, invaluable, almost-accidental modern history of Britain that's available to all.
   

And finally: some DJs just press play. A.N.I. is not one of those DJs.

All the best,
