My side project is a text RPG with no graphics, so I built a tool to help me market it. I have a side project that's a text-based, LLM-powered RPG. It's entirely text, with no graphics at all. It turned out to be a real problem the moment I tried to make any video content to promote it. It's surprisingly hard to put together a compelling clip when all you have is words on a screen. So I ended up building a second thing to solve the first thing: https://motiontext.video . It

Slide the green piece to the target with unique movement rules for each colored piece.

Obstruction - A daily sliding puzzle Obstruction is a puzzle where the aim is to slide the green piece to the target. Sounds simple, but pieces have movement restrictions depending on their colour so the solution isn't always as easy as it seems. With a fresh puzzle every day and a short playtime, this game can become a fun habit that slips right into your daily routine. Compete with your friends to see who can solve it in the shortest time or fewest moves using the share button

Benchmark AI models by having them animate a 3D banana plant's full lifecycle.
fran-mora · HN
I gave 5 AI coding agents one prompt: grow a banana plant through its whole life in three.js: sprout, leaves, flower, fruit, rot, then pups that restart the loop. It's deceptively simple and yet very hard to get right from procedural code: you have to write working three.js and understand how the plant is actually built; how it hangs, ages and decays. Get the biology wrong and the code renders something weird. These are agents, not bare models (Claude Code and Codex for now). They can use tools, including playwright to check their work and improve it.

As a 43-year-old father, building a game and creating characters of animals, with your son, is a pretty cool thing to tick off the bucket list ☀️

Would you use a brainstorming/planning/ideation tool for side projects? This is not a new idea, and I know we see posts about something similar about once a month. I do think I took it farther than others I've seen, but either way I'd still be interested in feedback on this one. Backstory: I've been building side projects with AI a lot (who hasn't?) and I realized that over the past year I've gravitated toward a very structured approach for building new ideas. I define it, research competit
