Using the @openai Codex app, I was finally able to create the most faithful Pac-Man clone for the Commodore 64 version I played about 40 years ago! My previous attempts always missed something or didn't work exactly as intended. Codex also packaged it into standalone Mac app!

One of my favorite games that I played about 40 years ago was called Boulder Dash. I first played it on a Commodore 64, then later played a version on an Amiga computer. Now I’ve just created a better Mac version using GPT-5.5 Codex! This is so incredibly cool time be alive!

I put Codex into DOOM using Codex app server. Codex modified the actual game files and modified the game engine to render the terminal interface natively and have Codex engage with the game.

Hacking a Polaroid printer with Codex: the printer didn't have a Mac app or any way to connect to a laptop, so I got Codex to reverse engineer the bluetooth connectivity and build a native swift app. We then also built a Codex skill to get it to print something fun. With coding assistants you can now avoid being stuck with badly design native software, but build something yourself that you'll like and enjoy - whether it is a printer, digital photo frame or some other IoT device gathering dust around the house. It is really not that hard to do anymore.

With the Codex app you can: - Multitask effortlessly: Work with multiple agents in parallel and keep agent changes isolated with worktrees - Create & use skills: package your tools + conventions into reusable capabilities ⁃ Set up automations: delegate repetitive work to Codex with scheduled workflows in the background

The Codex App Server is massively underrated. You can inject Codex-level intelligence into any platform using your ChatGPT account. I embedded it into Chrome… and it works flawlessly. And yes… it’s 100% open source.

💡 Little launch day OpenAI Developers Codex productivity tip You can add ?prompt= into the Codex URL. I created a hotkey using @raycast Quicklinks to take the selected text and open it in Codex. Great way to quickly kickoff tasks from error messages or GitHub issues
