🏂❄️ Ski Jump Simulator 🏂❄️ This was my first real wow moment with the new Codex app + skills + codex-5.3. I was able to ship a playable, physics-based sim even though I’ve never built a game before! 🧵on tips / lessons learned ski-jump-sim.vercel.app

#mmselfie It’s a beautiful day for NCAA basketball! #ArchMadness #ArchesUp

I've been trying out Shortcut with GPT 5.4 today. It's super impressive, nice job on this!

@bfioca Ha I forgot about that one! Definitely lower on the list

@kleneway World Games was a bit weird but they had caber toss

@bfioca That and Summer Games were pretty incredible. Best C64 games by a mile

@kleneway omg I was wondering if that's where this was from! I loved that game

p.s. I have to shout-out my inspiration for this game. 1985's classic "Winter Games" for the Commodore 64! So many hours trying to time it juuuust right to hit that red flag!

But overall, it was very fun to build a full working game end-to-end and Codex is surprisingly good at making games. Give it a shot! My high score is 112. If you beat it, reply with a screenshot 😄 ski-jump-sim.vercel.app

Oh no way it worked lol. Shoutout to ClawVault for the "primitives" idea. It even one-shotted out a swift app for the menubar, and just for fun I made a Remotion video of the readme! 😂 github.com/Versatly/clawv…

Weekend project - cron job to screenshot my laptop every five seconds, then use a codex automation to take notes and eventually create skills for my repetitive tasks.

I asked Codex to describe its latest changes as a RevealJS presentation. Top tier results. Is it maybe a bit too far to start asking for Remotion video explainers next? 🤨

@realchillben This is so true! Last weekend was rewriting OpenClaw to Python + max security + skillmaxxing, this weekend is setting up Codex app folders for each account plus building a non-creepy version of Microsoft’s recall feature.

things are moving so fast nowadays that I need one day out of every weekend just to find the optimal new setup that works best

@TheRealAdamG @AcerFur My #1 takeaway after two months in the job.

@AcerFur I’m on my 5th year at OpenAI and I can vouch for employees being not only the friendliest, but also the kindest and most thoughtful people I’ve worked with in my career.

OpenAI people have been some of the friendliest people I've spoken to :)

@steipete @OpenAI @openclaw This feels like OpenAI’s Instagram moment. Huge congrats and welcome to the team! 🦞

I'm joining @OpenAI to bring agents to everyone. @OpenClaw is becoming a foundation: open, independent, and just getting started.🦞 steipete.me/posts/2026/ope…
