Earlier quoted context omitted.

> "Oceans" is a kinetic sculpture that embodies the dynamism of the world's oceans within the arid landscape of Las Vegas. Crafted from 483 motorized elements known as "Brixels," this piece mimics the movement of the sea's surface. The sculpture is alive with the pulse of the planet's waters, ... All I can see are bars of gold.

BREAKFAST (AKA Zolty) here. The “ocean” aspect of the piece is in how it moves and the real-time API data that drives the wave-like motion. It grabs live tide data from a different coastal city each minute and changes based on that. The gold and marble bricks took inspiration from the Fontainebleau art deco style of their original Miami hotel (this piece lives in their Vegas location). Here’s a clip of it moving (doe…

Whoah!

Sorry, I was half joking, half of me gets the metaphor, but the other me is seeing a wall of bricks of gold in a Las Vegas casino and gets another metaphor.

Either way it's beautiful!

I have a question about those wire ferrules they said they were using: I occasionally connect wires to terminals, but - I've never used ferrules: I just self-twist the thin strands, push the thing in, and use the lever or tightening screw depending on the terminal's mechanism. Why would I use a ferrule? Or perhaps, under what circumstances is that advised? PS - Link to the ferrules they mentioned: https://www.amazon.…

The wire will crush over time and the connection will become looser. That will increase the resistance of the connection and in high current applications will cause heating. If you're really unlucky it will cause a fire.

I guess that's theoretically possible, but - I've not known this to happen anywhere in my lifetime, and I've not seem use of ferrules in wire terminals anywhere.

Ferrules often have insulating shells around the base which are good strain relief. Ferrules also evenly distribute the clamping force and prevent crushing of the strands. Ferrules solve the problem of having to align the threads every time you re-post them in a terminal block.

I wonder if crushing is more of a phenomenon when you have a lever you're encouraged to push down to a flush position, rather than a screw you tighten and have tactile feedback regarding the difficult of tightening further.
