Now that's an unbrella. 135 kmh in a wind tunnel and you can even take it skydiving. :oldtongue:

I hope they've had an even bigger umbrella with them while shooting the skydiver scene!

Dutch Singing Road. :oldlaugh:
Makes you wonder what bureaucrat thought this was a good idea. :doh:
Take the highway past the Dutch village of Jelsum and the road will play you a tune.
Created by strategically laid "rumble strips" as a way of livening up journeys across the flat landscape, the novelty has worn thin for locals who say the constant droning melody is driving them mad.
If hit at the correct speed - the 60 kph (40 mph) limit - the road will sing out the anthem of the Friesland region - a northern part of the Netherlands that has a distinct language and culture.
But it is loud and the sound travels, and locals say the musical road had created a never-ending cacophony that keeps them awake at night.

Really annoying sound :biggrin:, but still very cool!

Demonstration of the third version of Rhythmicom built by Leon Theremin at Moscow State Conservatory in early 1960-s. The first Rhythmicon was developed by Leon Theremin for Henry Cowell in 1932. It was the first rhythm machine ever built.



EDIT: A more hightech rhythm machine: EKO COMPUTERHYTHM

I worked (installed modern data processing systems not related to fire-control) on all the BB-62 class ships in the 80's when they were pulled out of mothballs again for active service. Most of the old 'analog' computers were still operational (with upgrades to automatically input signals from modern computers) to find firing solutions for the big 16 inch guns. Synchro data transmission links were used to slave data to the analog machines. http://www.eugeneleeslover.com/ENGINEERING/OP2074.html

I hope they're in a museum somewhere !

An old friend served on the Missouri in WW2 working on those mechanical computers.

As recently as 70's we had mechanical analog boiler controls that used compressed air , bellows, cams and levers .
Pneumatics works fine, is impervious to EMI, just needs clean dry air. The steady 'hiss' when all is going well is comforting.

For some things it's better than Fortran.

This video is beyond weird... o0)

What did we learn here? Always keep topologists busy, for otherwise they might produce youtube videos!

They should arrest him, those dance moves should be banned forever.

 
I'd wager the girls were not favorably impressed.

I'm guessing I'm overqualified to be an FBI agent. :biggrin:

Denver Post; "An off-duty FBI agent allegedly accidentally shot a man in the leg early Saturday after the agent’s gun fell from his holster..."

His holster looks suspiciously like the crack of his butt. o0)

ps. Do they not teach FBI agents about the "safety switch" on a gun? Seriously. It's been 40 years since I last took a class on handguns, and even I remember that. :rolleyes:
