Hexcalibur
Pixel art editor with a live 3D preview, in your browser
What it does
Hexcalibur is a browser-based pixel art editor for game artists. Paint block textures in 2D and watch them update live on a 3D block, animate sprites on a frame-by-frame timeline, and build tilesets with autotiling. Everything is organized as packs - manage and export a whole texture set as one unit, with engine-aware exports for Minecraft (Java + Bedrock), Tiled, Godot, Unity, Three.js, and Babylon. No install, humans place every pixel. Free to start, Pro when you need more.

Open-source pixel art editor with animation and auto-tiling tilesetsAug 2026 · simplepixelart.com · ▲8Hi HN! I built a free pixel art editor that runs entirely in the browser — no install, no signup, no watermark. The frontend is open source (MIT): https://github.com/comficker/simplepixelart What it does: - Sprite editor with layers, selections, mirror drawing, and an infinite-canvas workspace (multiple boards on one desk) - Frame-by-frame animation with onion skin, per-frame duration, GIF and spritesheet export - Tileset builder that auto-generates Wang-16 and blob-47 terrain sets from a single base tile — exports Godot 4 TileSet, Tiled .tsx, or PNG+JSON — plus a tilemap…

I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…
