I happily picked up two used Nvidia Tesla P40 GPUs. I knew the P40 was old and ridiculously overbuilt. What I did not expect was how long the GPUs would become once the coolers were attached. Tried putting them in the case. Nope. The cooler end would not fit. I thought about it for about 10 seconds. Turns out the bottleneck was not the human. It was the case. So I grabbed a hammer and pliers and destroyed the front section of the case. After that both P40 GPUs fit perfectly. Put the cover back on and you cannot even tell from the outside. Apparently hardware fits if you hit it hard enough. Good experience.

retro-design-system 53 retro UI themes you can use in your project or hand to an AI coding agent Each theme is a standalone HTML/CSS file with design tokens, components, and patterns. Styles range from Windows 95 and CRT terminals to Mac OS X Aqua, GeoCities, and Bauhaus. Open a theme in your browser with no build step or dependencies. Reuse its palette, borders, shadows, and typography in your own components. Give a theme to Claude, Codex, Gemini, or Cursor to generate pages and components in that style. github.com/NovusGFX/retro-de…

morphin Turn your own sprites into pixel art transitions for your website Morphin is a JavaScript tool that creates animated CSS transitions from your sprites. You can embed the result in a website using CSS alone. Add your sprites, then copy the generated code into your site. The project also has an online demo. github.com/javierbyte/morphi…

pixora-icons 16 bit pixel icons for Linux that keep familiar app designs recognizable The theme stays close to original application icons while giving them a pixel art style. Pixora uses fixed colors, while Pixora Dark uses the same artwork with a dark theme fallback. In supported KDE Plasma 6 applications, Pixora Accent matches folder bodies to your KDE accent color. It needs no background service or regeneration for each color, though errors and visual inconsistencies may occur. github.com/tsora1603/pixora-…

kiln Build 3D assets locally with a coding agent and keep the source for later edits Your coding agent writes JavaScript using Kiln's geometry and material helpers. Kiln runs it, returns rendered views and structural checks, and exports a GLB. The editable source stays available for refinement. CPU rendering lets you review geometry without a GPU. It runs locally through MCP, the CLI, or a JavaScript/TypeScript SDK, with no account required. Your coding agent supplies the model, so Kiln needs no separate model API key. github.com/instruktlabs/kiln

Nova3D Build editable 3D worlds from code for design tools and robotics simulators Parameters control dimensions, materials, physical properties, and motion. You can vary selected parameters while keeping others fixed, and reuse components across designs. People and AI agents can work simultaneously on separate branches of the same world. Versions preserve source, parameters, build outputs, and validation results. One source targets Blender, MuJoCo, Isaac Sim, Unity, Unreal, and more. Simulation checks movement, collisions, and interactions. github.com/RareSense/Nova3D

UnityGLTF Import and export glTF assets at runtime in Unity, including WebGL This glTF 2.0 library is written in C# with no native dependencies. It supports animation with multiple clips, skinned meshes, and blend shapes. Custom plugins and callbacks let you adapt import and export to your project's pipeline. It can coexist with glTFast in the same project, so you can use glTFast for import and UnityGLTF for export. github.com/KhronosGroup/Unit…

Game Assets Maker Turn video footage into transparent animation frames for your game Start with footage against a plain background color. Extract frames, remove the background, clean up holes and align the results, with a preview at each step. Frames can share a canvas size for playback, or use tight crops to save space. JSON offsets let your engine prevent jitter. Local extraction, background removal, alignment and trimming are free, with no login or credits. Processing works offline once the model is ready. github.com/hyhy111/game-asse…

RealWorldMC Explore real cities in Minecraft and place blocks inside Street View RealWorldMC is a Minecraft Java mod that streams real 3D scenery from Google or Cesium. Fly over cities and mountains, or travel to a place by name or coordinates. Inside Google Maps Street View, you can move using its arrows, place blocks and spawn mobs. Each new world starts at one of 100 locations. github.com/Teddy563/realworl…

vintageJS Vintage photo effects with consistent grain from preview to full size This TypeScript library applies retro effects using canvas. Pass an image URL, image element or canvas element, then adjust grain, light leaks, vignettes, brightness and grayscale. Film grain scales with image size and stays identical on every run, so previews match full size photos without flicker between renders. Blob output works in Web Workers. Effects run pixel by pixel, which can block the main thread on large photos. github.com/rendro/vintageJS

Fusion Pixel Font Latin and CJK pixel text with fixed or proportional widths Choose 8 px, 10 px, or 12 px. Monospaced mode uses half or full character widths for strict alignment. Proportional mode sets widths by glyph shape and adjusts kerning for natural spacing. You can preview the font in a web playground. Godot and Unity localization examples are provided. github.com/TakWolf/fusion-pi…

NOFX Approve each trade or let a strategy run continuously NOFX is an open source AI trading assistant that runs on your own machine. It covers US stocks, commodities, forex, and crypto. Frontier requires approval for each trade. Plans show entry price, stop loss, targets, position value, and estimated margin. Generating a plan does not submit an order. Autopilot can place trades while a strategy runs. A dashboard shows positions, performance, and decision history. Wallet private keys and exchange credentials are kept out of model prompts. github.com/NoFxAiOS/nofx

Gazebo Sim Build robot simulations with physics, sensors and custom controls Gazebo Sim is an open source robotics simulator with multiple physics engines. Its graphical interface lets you create, inspect and interact with simulations. Simulate cameras, laser range finders, contact sensors, IMUs and GPS, with optional noise in the sensor data. Custom plugins let you control robots, sensors and environments. Use models from Gazebo Fuel or build new ones with SDF. Simulations can also run on remote servers through Gazebo Transport. github.com/gazebosim/gz-sim

img2css Turn an image into CSS made entirely of box shadows The online tool resizes your image, then represents each pixel as a box shadow on a single pixel div. This uses no image tag or background image. You can also choose base64 output, which embeds the entire image file inside an image tag without external hosting. github.com/javierbyte/img2cs…

deja Recover overwritten code and carry context between coding agents deja makes local session histories from 43 coding agents searchable, including Claude Code, Codex and Cursor. Indexing and search stay local, with no LLM calls. You can hand an active session's goal, decisions, touched files and open work to another agent. It can recover code overwritten before a Git commit and identify the session that wrote a line or the text it replaced. Credentials are stripped during indexing. github.com/vshulcz/deja-vu

FastNoise2 Build noise graphs visually and load them directly into your app FastNoise2 is a C++17 noise generation library. It keeps noise generation, arithmetic and blending in the same SIMD pipeline to reduce memory allocation and bandwidth use. Build graphs in code or with the visual Node Editor, which previews textures, heightmaps and meshes. Save a node tree as a compact string, then decode it at runtime in your application. It includes Perlin, Simplex and cellular noise, with operations for combining noise and changing its shape. github.com/Auburn/FastNoise2

Claude animation skills Six Claude Code skills that make reel animations with no footage at all Ask for a map route from home to the gym, 2.8 km, and Claude writes the spec. It renders the animation on your own computer and checks it against Instagram's safe area. The set covers a 3D cartoon "what if" explainer, a stick figure reel and black and white line art. It also has a 3D map route, an exploded phone with labeled parts, and a counting line graph. Output is 1080x1920 at 30 fps. The 2D ones render in about 10 seconds and the 3D ones in about 1.5 minutes, with a local voice and no API key. github.com/artemnovitckii/cl…
