What Opus 5.5 made
Dark green and gold with serif numerals. A counter starts at $100.00 and ticks up year by year ($114.49 after two years) while a bar chart grows to $761 at year 30 — the correct figures for 7% compounded annually. The takeaway card reads “Time does the heavy lifting.”
The model wrote the whole video as Canvas 2D animation code; the browser rendered it frame by frame and encoded the MP4. You can also watch the original live render, drawn from that code in your browser.
