A reading-notes app took three months to build and returned about $1,000 across a year. The pixel desktop pet app that followed it made roughly $150 in 24 hours, with no server, no accounts, and no support queue. Everyone read the thread as a lesson about cuteness. It isn't.

Simon is a designer. His cat sits on your desktop and reacts to three things: your mouse, your typing, and what your AI agents are currently working on. Stack isn't disclosed. The only architectural fact he states is that there's no backend and nothing leaves the machine. macOS is implied by commenters, never confirmed by him. Roughly half the comment thread argued about whether it was a keylogger. People bought it anyway.
What he's actually selling (hint: not a cute AI desktop pet)
The product isn't the cat. The product is permission to occupy screen space on a machine that would refuse a productivity tool the same access.
Here's the mechanism. Millions of people now spend hours a day watching coding agents run, with nothing on screen acknowledging any of it. That's newly created dead ambient space, and it didn't exist two years ago. A person who can draw is exactly the person positioned to fill it. Cute desktop pets have shipped since 1997, so nostalgia isn't the edge. A desktop pet that knows when your agent is mid-run is about three days old, and it's the only part of this product nobody in the thread bothered to price.
The second half of the mechanism is what the product demands back. No backend means no migrations, no uptime, no sync-bug support queue. That's near-total margin per sale and, more importantly, a product that cannot page him at 2am. Most $1K/year apps aren't failures of demand. They're jobs that pay $83 a month.
A product with a server has a shift schedule. A product without one has a price.
