Yes, I could go into a 9-5 and take a paycheck. Or I could ask Opus 5.5 to: - Build a native mac app for visualizing music - Model a robot head in Blender - Use my own track from 2018 and hook it up And hope things work out.

Opus 5.5 is probably the biggest jump in output quality I've seen lately. Built this in HyperFrames for Cosmos, 2 prompts only. No references at all. Prompts below.

On Omarchy for the last few days. Wanted a dock, so I built it with an agent. Wanted an infinite canvas, so I built it with an agent. Want a new file manager, being built now. Yes it's not super polished yet. But there is no going back to a locked down OS. You build your own apps. You build your own OS. PS: Posting from a MBPro because it's 2:43AM and I can't begin to learn Kdenlive now.

I wanted infinite canvas for my desktop. So I built it with Omarchy and Opus. I'm calling it Phantomat. Grab here: Thanks for all the feedback, gl and hf.

Always loved these topographic maps and wanted to create something similar with Three.js. 3 hours in Claude Code with Fable.

There is something to this light concept! My last version of it had too much visual noise. Html-in-canvas, Three.js, Fable.

Masking videos is underused, lots of creative opportunities. Built this with Grok Imagine, Kling O1 for restyling the original video perfectly and Fable.

Spent a few days perfecting this guy! The movement is so smooth, love how it turned out. Started with Opus 4.8, but needed Fable and Astra to get it right. Wish I could say any of this was a one shot. Not even close.

Saw the great match visuals from Alexander Bogachev and had to try building something similar. Argentina - Switzerland game, Three.js scene. Plane is displaced by game data. Crest position is based on the ball. Height is based on momentum.
