It has been such an honour to be on the Beyond Tellerrand stage. I've given dozens of talks and this one felt very much like a personal journey through some projects I never meant to show on stage.

I had so much fun creating all of this and I think it shows in the video. Thank you, Marc!

I can't believe this actually works.

The game loop sends renderer commands to an orchestrator that fans out the commands to multiple local completely independent renderers.

Each renderer gets the same commands and can decide to override the camera position.

One of the things I started doing recently is to add recording and visualisations straight into my demos. Great to export and then include in a talk.

In this case I am showing 4 different renders, from my original oscilloscope version of DOOM and several intermediate steps of the CSS renderer.

I guess this is a sign that I should start with my #CSSDay presentation 😬

@Una I might need to recount, but I think we cover 34 (!!) new #CSS and Web UI features in 45 minutes in this talk.

Every demo shown in the talk has a link, and there's also a ton of links to articles and explainers included throughout.

And yes, we also show compat tables and baseline indicators.

Here's the recording of this year's “What's new in Web UI” talk @Una and I gave at Google I/O earlier this week.

Very happy with how it went, and I think you might find it useful, so give it a watch 😊

#ChromeDevRel #GoogleIO

Half an hour to go before @Una and I take the stage at #GoogleIO to give you an update on CSS and Web UI.

I just saw the full schedule for #cssday and oh my... just look at all of those names. 🤩 The best and the brightest of CSS all in one room and then there is also me. No pressure, no pressure... It's gonna be fine 😅

Been using Claude Code to add network support to cssDOOM and... I have opinions:

Claude is brilliant and able to solve complex problems. But it uses band-aids and shortcuts to achieve that. It is an extremely fast lazy programmer that is able to create technical debt quicker than any human being.

Multiplayer cssDOOM on your phone? Yeah, it works. Just no good way to control it. But yeah. It can render two scenes side-by-side without any major issues. 🤯

If only you could start a network game from your phone so your friends can join you… coming soon 😱

In theory it could do four players. But two is pretty much the maximum the browser can render simultaneously.

But that is okay. Rendering one DOOM in CSS is already crazy. Rendering two at the same time is insane. Yet it works.

On a side note: my eleven year old is already beating me.

Made progress with cssDOOM last evening.

Created a special multi-player deathmatch version for CSS Day that runs in kiosk mode. It uses a video wall controller to split up the screen into sections. On the computer it is just one full screen window, but it drives two separate screens.

It is always fun to talk about my weird little projects, but this turned in to such a lovely chat. Want to know a bit more background about cssDOOM, my bad clock project and CSS on oscilloscopes? Check it out!
