16:T5f6,Hi, I built Ghana House Planner https://ghanahouseplanner.com to help individual homeowners, builders, and DIYers in Ghana/Diaspora plan and estimate residential construction costs. The floor plans are built to comply with Ghana building codes.

It lets users:

- Select common house types (e.g., 2-bedroom traditional, luxury, etc)

- Customize materials (foundation, roofing, finishes, etc.) using up-to-date local pricing (updated monthly)

- See real-time cost breakdowns across categories (steel, electrical, plumbing…)

- Export or share estimates

- Manage different phases of construction

The rendering is built with React and is intentionally lightweight— the 3D viewer (currently under development).

The platform is free to use except for project management and using the LLM to define your house plans.

Current features include:

Region-aware material database (30+ items, sourced locally)

Modular cost estimator with category filters

Mobile-responsive UI (simple, fast, no bloat)

Next: job directory & marketplace (for local artisans & suppliers)

I would be happy to receive your feedback — especially on UX, scalability, or how tools like this could serve other regions. I believe this is also useful for Nigeria and potentially other tropical countries especially for the floorplans

https://ghanahouseplanner.com17:T55e,I've been recreating the original MacPaint in the browser on and off for a few years. It's still alpha quality, but I'm finally ready to share it more widely.

The goal was pixel-perfect accuracy, so I spent a lot of time with Atkinson's original QuickDraw source code, emulators, and my iBook G3 to get details like font rendering and the shape tools exactly right.

Some technical notes:

- Font rendering was surprisingly tricky; understanding the original pipeline's quirks
