A 3D island town built in about 8 hours with $1,874.40 worth of tokens

A first-person game was built with Three.js, a tool for drawing 3D on the web. You carry a torch and a sword and walk along a village road to a distant castle. It took 40 minutes, including the music and art assets generated with an image generation AI.

Even with the music and art handed off too, a game with a real atmosphere comes out in under an hour.

Willowmere is a cozy 3D pixel art game. You move to a small seaside town, fix a lighthouse that has gone dark and bring back the lantern festival. It has farming, fishing, cottage decorating, and befriending the residents and a cat, and it also plays right away in a phone browser.

The $20 monthly plan alone is enough to finish a game with plenty to do in a few five-hour sessions.

A developer made the trailer for the game they are building with Opus 5.5. In a field that looks cut out of paper and pasted together, a snail with a 'BOB' sign faces a hooded figure holding a 'YOU' sign.

A solo game developer can work with the model to make the video that promotes the game too.

Opus 5.5 made a UI motion video using only code. In it, a single shape keeps turning into screen elements such as a button and a music player. The video editor After Effects was not used at all, and the author also shared a prompt template for making the same video again.

Designers used to polish UI motion scene by scene in dedicated software. Now it can be made with a single prompt and an HTML file.

A 3D game was made with Opus 5.5 in the style of Nintendo's Splatoon: two teams compete by shooting ink to paint the floor in their color. It has a time-limit timer, a minimap and a special-move button, and anyone can go to the web address and play right away.

The rules and screen layout of a famous console game can be carried over into a game that runs in the browser with no install.

Opus 5.5 was given the research paper "Regularized Recursive Self Improvement of Agent Harnesses" and made an 8-minute summary video in the style of the math explainer channel 3Blue1Brown, with shapes and arrows moving on a black screen. The video illustrates how a harness (the execution framework wrapped around an AI so it can do work) analyzes its failures and fixes itself step by step.

Turning a difficult paper into an educational video anyone can watch can be done automatically, with no human work.

With Opus 5.5 set to Max effort, its deepest thinking level, a single request asked for a 15-second motion graphic like a showreel (a short compilation video that shows off your skills) to attach to a résumé. The result was a video of bold CLAUDE lettering and the phrase motion designer moving across a red screen.

A self-introduction video that motion designers put real work into can come from a one-line request.

Asked to design a microduck that could be built from real LEGO, Opus 5.5 designed a life-size model using 1,113 real LEGO parts. It checked 3,204 connections, found 0 places where parts collide, confirmed that every step can be assembled, and confirmed that the center of gravity sits inside the feet. It then made a 141-page LEGO-style manual with 237 steps, priced the parts in the browser and prepared an order on BrickLink (a LEGO parts marketplace).

The whole process of actually building a LEGO piece can be handed to the model, from design and structural checks to assembly instructions and parts ordering.

The user put someone else's prompt into Claude Code almost unchanged and stepped away. Over about 1.5 to 2 hours, it made an explainer video for the meetup app Friendr.nl on its own. It made the script, hand-drawn collage art, voice, music and sound effects, built it all as plain JavaScript animation synced to the speech and exported it as MP4. It also had another model review the draft and fixed the problems that review found.

With just one borrowed prompt, you can get a ready-to-use explainer video for your own service for about $4.

This scene was built with Three.js (a JavaScript tool for drawing 3D in a web browser). You steer a boat down a river through Japanese scenery. The weather changes and the light shifts between day and night. It has reflections on the water, a pagoda, cherry trees and 3D people, and you can try it right away on a public site.

A 3D scene with water reflections, physics, weather and buildings can be made to run right in the browser with no install.

This video in the style of an SNES (Nintendo's 1990s game console) game tells the story of Sydney, the 2023 Bing chatbot, fighting Sam Altman and then facing Claude. Several agents (AIs that carry on through multiple steps on their own) split up the characters, music and battle scenes and made everything in code. The user did not provide a single image or sound file.

Character art, background music and battle staging can all be handed off at once, so one person can make a retro game-style video alone.

Opus 5.5 was asked to make a game called 'The trolley problem is not a problem'. The trolley problem is the ethics thought experiment where you switch tracks to choose who to save. On screen, a mine cart racing down the tracks smashes whatever blocks its way to build combos. The screen also shows health, gold, 30 sections, the distance left to the boss and a lever for switching tracks.

A one-line game idea that twists a famous ethics problem became a 3D game with health, combos and boss stages.

Alongside GPT-6 Astra, it was asked to make five games, each from a single prompt: a 2D platformer, a racing game, spaceship combat, a first-person shooter and a stone golem boss fight. No human wrote a single line of code. The 3D assets (the character and object models in the games) were not downloaded. All of them were made from scratch in Blender (a 3D creation program).

It shows that five games in different genres can be filled out with one request each, from model building to graphics, sound and game rules.

Claude was asked to show what was inside its own mind, and Opus 5.5 made a video. Tiny characters densely fill a dark screen to form golden shapes, and short subtitles run beneath them.

Left to decide how to depict the invisible inside of an AI, the model chose the staging itself and showed it in a single video.

A hand-drawn, collage-style animation on the theme 'What is the purpose of life?' was built in pure JavaScript. From a single prompt, Claude Code worked alone for about 1 hour 20 minutes on the script, drawings, voice and animation. Fees for 8 external APIs (channels for borrowing features from other services) came to $3.21, and it used about 10% of the 5-hour usage limit.

Even while no one is at the desk, a short video with everything from planning to drawings and voice can be finished for the price of a cup of coffee.

Opus 5.5 made a pixel art scene of an island floating in a rainy night sky. The lit house, the campfire, the pond, and even the bones and crystals underground were all drawn in TypeScript (JavaScript with added type rules) code, and it took about 10 minutes to finish.

A pixel art scene good enough for a game background can be made with code alone, without a single image file.
