Explainers0:47Tried Opus 5.5 to explain the Mid-Autumn Festival 🌕
From ancient traditions to mooncakes and family reunions, I turned the story into a short animated video.
The message is simple: No matter how far apart we are, make time for the people we miss.
What do you think of the result?
Explainers0:35Asked claude Opus 5.5 to make an explainer on how a mechanical keyboard works.
It wrote the music in code, used real switch recordings as the beats, built the 3D in @threejs and timed every cut to the beat.
No stock footage. no editing app.
What a time to be alive!
Explainers0:44I TRIED MAKING A 3D MOTION GRAPHIC WITH CLAUDE OPUS 5.5. THIS IS WHAT CAME OUT.
The idea was simple: start at my desk and don't stop zooming until we hit a single atom inside the CPU.
Opus 5.5 took it and just kept going.
Into the PC case. The cooler lifts off. The CPU under it. The metal lid comes off. Then the silicon die, one core, the copper wiring stacked on top, rows of logic cells, the fins and gates of the transistors…
…all the way down to one silicon atom, bonded to its four neighbours.
One continuous shot, no cuts. The ruler on the right tracks the scale the whole time: from abo…
Explainers1:00From Cabo da Roca to observable universe.
I gave opus 5.5 old prompt I prepared for Fable but I was not satisfied with the results. I asked model to create a cinematic film that zooms out from a hillside on Earth to the full observable universe using @threejs No external assets.
