Build a complete 3D browser game in a single HTML file that I can play right away. Concept: a low-poly endless runner where I steer a small spaceship through a canyon, dodging rocks and collecting glowing orbs. Speed slowly increases. Requirements: - Keyboard controls (arrow keys or A/D) and touch controls for mobile - Score, high score, and a game over screen with restart - Sound effects and a simple looping soundtrack generated in code, with a mute button - A polished start screen with the title "Canyon Run" - Smooth camera, particle effects when I collect an orb or crash - It must look good enough to show in a YouTube video: strong colors, fog, glow Play-test your own logic before you finish. No placeholders, no "todo" comments. Deliver the finished game.

This is a hand-drawn sketch of an app I want. Turn it into a fully working web app in a single HTML file. - Follow my layout as closely as you can, but make it look professionally designed - Every element in the drawing must actually work: buttons, lists, checkboxes, counters - Save my data so it is still there when I reload - Make it work well on a phone - If something in my sketch is unclear, pick the most sensible interpretation and tell me in one line what you assumed Deliver the finished app, not a mockup.

Design a 3D-printable desk stand for my phone with the word "FERDY" embossed on the front. Deliver one HTML page with: - An interactive 3D preview I can rotate and zoom - Sliders for phone width, viewing angle and stand height that update the model live - A button that downloads the current model as an STL file ready for a 3D printer Design rules: prints without supports, minimum wall thickness 2 mm, stable with a large phone in portrait and landscape, with a cable slot at the bottom. Check the geometry yourself before you finish and tell me the recommended print settings.

Design a live YouTube subscriber counter for my desk that a beginner could build in an afternoon. Deliver one HTML page with: 1. A parts list with approximate prices in euros (ESP32 board and an LED matrix display) 2. A clear wiring diagram drawn as a graphic, with every pin labeled 3. The complete firmware code, with comments, that connects to WiFi and shows the live subscriber count 4. Step-by-step build instructions 5. A working on-screen simulation of the LED display so I can see how it will look, including an animation when the count goes up Double-check that the pins in the diagram match the pins in the code.

I am going for a coffee break. When I come back I want a complete, launch-ready business concept. Work on your own and do not ask me questions. Make sensible decisions and note your assumptions. Business: [YOUR IDEA, for example: a subscription box for home baristas in the Netherlands] Do all of this: 1. Research the market on the web: competitors, prices, gaps. Use real sources. 2. Choose a brand name, tagline, colors and tone of voice. 3. Build a complete landing page with real copy, pricing section, FAQ and a signup form. 4. Create a pricing and margin calculation in a spreadsheet. 5. Write a 5-email launch sequence. 6. Write a 30-day launch plan with daily actions. Check your own work at the end and fix what is weak. Then give me a short summary of what you made, with everything ready to open.
