An explorable 3D island world that holds 60 FPS at 1440p

Dan built an explorable island in Claude Opus 5.5 using subagents over about eight hours, spending roughly $1,874 in tokens. Birds dive into the ocean, crabs burrow as you approach and fish swim beside a whale, never dropping below 60 FPS at 1440p.

Ever wonder what $1874.40 of Opus 5.5 tokens looks like?

Wonder no more.

I highly recommend watching the whole video on 1080p on a large screen with sound on.

Pay attention to all the little details.
- Birds flying and diving into the ocean.
- Cloth, signs and lights swaying in the wind.
- Crabs scuttling along the shore and burrowing when you get close.
- Fish swimming alongside the whale.
- Lights illuminating the dock at night

Then zoom out and see the entire island. Never dipping below 60 FPS at 1440p resolution.

Yes, there's a few bugs and visual artifacts, some textures need improving, the shorelines waves sometimes look funny, but these are so trivial to fix at this point.

FYI I'm on the $200 subscription plan. This used 59% of my weekly usage and took 2h 7h of API time using multiple subagents, about 8h in real-time.

There was extremely little technical direction here. 99% of my prompts were "Add X and Y" or "This looks weird, make it better".

It's a great time for hobbyists, bad time for professionals. This experiment has further cemented my view that technical creatives are about to experience a massive disruption.
