Holosticker is a browser-based holographic sticker studio developed by jal-co. It accepts SVG or PNG artwork, renders a PBR holofoil surface with view-dependent diffraction bands, thin-film iridescence, metallic flakes, and environment reflections, and supports pointer-driven tilt effects. The studio generates die-cut borders using an exact Euclidean distance transform with morphological closing for cut tolerance. It also provides ink-density control, triangle, square, and stripe refractor overlays with per-facet diffraction phases, and a 3D peel effect with a graded hinge bend, conical curl, and glossy foil-liner backside. Settings can be saved or imported as JSON, and transparent PNGs can be exported at 1024, 2048, or 4096 pixels. The static Vite application uses React, TypeScript, Tailwind CSS, shadcn/ui, and three.js, and is deployed on Vercel.

TokensBurned is a privacy-first tool that publishes AI coding activity on a GitHub profile through a live SVG card. It collects token counts and model metadata from AI coding harnesses, reduces raw sessions locally, aggregates usage into 15-minute buckets, and serves totals, activity heatmaps, harness/provider/model comparisons, and an optional site-wide rank. It supports native or official integrations for Claude Code, Codex, Gemini CLI, Cline CLI or SDK, and GitHub Copilot CLI, with OTLP or standalone CLI fallbacks for other harnesses. The tool uploads aggregate token counts, harness/provider/model metadata, hashed session identifiers, time buckets, and request counts, while its stated privacy boundary excludes prompts, responses, source code, tool payloads, repository names and paths, transcript files and paths, and API keys. Public display is a separate explicit opt-in tied to a verified GitHub account; users can build cards with selectable layouts, themes, heatmaps, comparisons, and rankings. It is distributed through harness plugins and an npm CLI, installs no cron job, daemon, proxy, or Git synchronization task, and is licensed under the MIT License.

Instant Spotlight is a QR-code photo-sharing system for events and venues. Guest photos appear on venue screens, while the system captures guest contact information for marketing, enables tipping for the guest of honor, and emails the gallery to support review requests.

GyroidVault is a self-hosted 3D model library and print-management platform for organizing STL, 3MF, STEP, and G-Code files on local hardware. Its browser-based 3D studio renders STL and 3MF assemblies with contrasting-part colors, wireframe and X-ray inspection, physical dimensions in millimeters, measurements, notes, and print-history information; it also provides a layer-by-layer G-Code previewer with toolpath, Z-height, and temperature data. The platform indexes existing folders non-destructively using SQLite, supports background scanning for large libraries, duplicate detection with SHA-256 hashes, bulk tagging, custom metadata, role-based access control, expiring share links, and ZIP downloads. It can launch models in Bambu Studio, PrusaSlicer, OrcaSlicer, and Elegoo Slicer, and integrates with Moonraker/Klipper printers to upload sliced G-Code. GyroidVault is distributed as a Docker Compose deployment or a Node.js application, is also available through the Unraid Community Applications store, stores data locally without mandatory cloud accounts or telemetry, and is licensed under AGPL-3.0.

It's Giving is an open-source Python webcam application that recognizes facial expressions, hand gestures, and body positions, then overlays matching meme images or animated GIFs on the user's head. It uses MediaPipe face landmarks and blendshapes, hand points, body landmarks, face-relative measurements, tongue color, and hand speed; its calibrated version records seven seconds of the user's neutral expression and evaluates later expressions as deviations from that baseline. An ordered pose-matching pass requires gestures to persist for a configured number of frames before triggering, and the overlay follows the user's face with alpha compositing and animation support. The application publishes the result through a virtual camera for Zoom, Meet, Teams, Discord, OBS, and other webcam-compatible software. It includes fourteen predefined reactions, preview-only and virtual-camera modes, keyboard testing and recalibration controls, and an assets directory where users can replace or add reaction images. It runs with Python 3.11 or 3.12 and requires a virtual-camera backend such as OBS Studio or v4l2loopback, depending on the operating system.
