As a historical note, the bouncing logo wasn't just for fun, but was important to prevent screen burn-in on CRTs. If you had a static image on a CRT for a long time, it could damage the phosphor. Sometimes you could even see the image when the screen was off! This was the original purpose of screensavers, which saved your screen from damage. Displaying a dynamic image prevented one part of the screen from being overu…

That you feel the need to inform us of this "historical fact" makes me feel especially old... having lived through the CRT -> LCD transition period when buying an LCD made going to LAN parties a lot easier

I finally threw out my $1500 Sony Trinitron 27" high resolution CRT this year.

It worked fine, felt like a huge waste of money. But it weighed over 100 pounds!

My wife's version uses SVG for scaling and is also responsive on resize. https://github.com/boglarkasebestyen/dvdscreensaver

Nice, a bit too fast on my machine though. It should probably use a time-based interval, rather than updating every frame.

It's just a less-than-ideal implementation, your CPU is most definitely not suffering. Here is a completely smooth version: https://codesandbox.io/s/nostalgic-cherry-wwpzj?file=/src/in... (I made the exact same thing last year as a joke for our team monitors)

This is definitely not smooth on iOS, on a brand new iPhone that’s arguably way faster than whatever system played the original DVD screensaver. On a technical note, not that there’s much you can do about this, but because you’re reading clientWidth and clientHeight each frame, you’re forcing reflow. A performant implementation would probably require avoiding the DOM altogether within the draw loop, so that would mea…

Looks great on my new iPad Pro, so I guess it was worth the money!

I still remember dragging my CRT around to LAN parties... oh the good old days... was such a pain in the ass though in reality...

I think my favorite contextual example of this is the opening line from Neuromancer: "The sky above the port was the colour of television, tuned to a dead channel." Means something very different now.

I wonder if 2000n years from now, scholars will be wondering over the meaning of that sentence, the same way that they currently discuss the meaning of "wine-dark sea" in the Iliad and the Odyssey (https://en.wikipedia.org/wiki/Wine-dark_sea_(Homer))

Too bad that you threw out. Those Trinitrons are still sort after for retro gaming. You could of sold it or given it away.
