COSMOCRYPT VT-80 is a retro-futuristic space terminal that encrypts and hides secret text messages inside digital images using Least Significant Bit (LSB) steganography. Styled like a flat 1980s monochrome CRT console, it converts text into binary and embeds the data directly into the Red, Green, and Blue pixel channels. The encoded image is exported as a lossless PNG and can be shared publicly before being decoded with the terminal's built-in laser scanner. The experience is enhanced with real-time digital signal processing effects, including a Sub-pixel Telemetry Microscope that magnifies pixels, highlights modified RGB channels, and displays the hidden payload bits. A Signal Interference slider simulates transmission noise by adding CRT static, radio hum, visual screen snow, and random bit-flips during decoding, producing realistically corrupted messages and demonstrating how noisy communication channels affect hidden data.

Mission Control is a realistic, web-based spaceflight planning and simulation dashboard. Design custom rockets, manage orbital mechanics trajectories, run pre-launch checkouts, monitor telemetry data in 3D, and explore the Solar System—all through a premium, dark sci-fi aerospace terminal HUD.

World Engine is an advanced scientific visualization and planetary intelligence platform that transforms Earth into a fully interactive digital twin. By integrating live telemetry from weather systems, aviation, maritime networks, satellites, geology, energy infrastructure, internet connectivity, supply chains, and environmental monitoring, World Engine allows users to explore, analyze, and understand the complex systems that keep our planet running. AI-powered layer fusion, historical replay, predictive simulations, and cinematic 3D navigation provide an unprecedented way to observe and interact with the world in real time.

Atlas transforms static codebases into interactive, glowing digital universes where you can navigate software like Google Maps. Instead of scrolling through thousands of lines of text, you can fly through 3D code cities of skyscrapers where building heights represent complexity, watch runtime execution paths pulse along neon roads in real time, scrub git history to watch structural evolution morph before your eyes, and command a flight-steered AI companion to fly you directly to target modules. It is a visual, living window into the topology of software.

NetSim Pro is a browser-based interactive network simulation platform that enables users to design, configure, and simulate virtual computer networks through an intuitive drag-and-drop interface. Users can build network topologies using routers, switches, firewalls, servers, and client devices, configure IP addresses, VLANs, routing tables, and firewall rules, then visualize real-time packet transmission, routing decisions, latency, congestion, and protocol behavior. The platform includes live monitoring dashboards, event logs, performance analytics, project saving and sharing, and collaborative editing. NetSim Pro transforms complex networking concepts into an engaging, realistic, and fully interactive learning and experimentation environment entirely within the browser.

Apex Aerospace Studio is a professional aerospace engineering platform that combines rocket flight simulation, aerodynamic nose cone optimization, and mission patch design into a single engineering workspace. Built with the look and feel of real aerospace software, it provides engineering-grade visualizations, analytical tools, and design utilities for students, researchers, and rocketry teams.io

This is zBot, a custom Slack bot built with Node.js and Slack Bolt using Socket Mode. It runs on your computer or a server and connects to your own Slack app using tokens from your workspace. It responds to seven slash commands: zping checks if the bot is online, zquote sends a random quote, z8ball answers yes or no questions, zstandup lets you log or view a daily task note, zremind sets a personal reminder that messages you later, zflip flips a coin, and zroll rolls a dice. To use it, you create your own Slack app from the provided manifest file, get three tokens from Slack, put them in a file called dot env, then run the bot with npm start. For it to stay online all the time, you deploy it to a hosting service like Hack Club Nest instead of running it on your own laptop.
