No, sorry. Also, it'll be in Danish.
Happy to catch up on a call sometime soon if you want though! Then I can share some of the things we've been working on.

Hah, this is genuinely bonkers.
Just now, I was adding screenshots of tldraw comp to a presentation about AI in teaching for highschool teachers. I use it as example of a Hypercard-like future where teachers may be able to make their own interactive teaching material. I should show fairies too.

Thanks for the mention! The hard work has been done by @maski89.bsky.social.
If you want some more details, I wrote this thread about it some weeks ago:
bsky.app/profile/clem...

Our goal has not been to make a 3D tldraw, but to imagine a system where you can seamlessly move between 2D and 3D.

Haha, very relatable

I should tag this thread with #uist2025

Here’s a paper preprint: pure.au.dk/portal/files...
The code (open source of course): github.com/Webstrates/S...

Spatialstrates is a collaboration between Aarhus University and Bangor University with @jensemil.bsky.social, @pwsbutcher.bsky.social, @ritsosp.bsky.social, and @nelmqvist.bsky.social.

Spatialstrates builds on a decade of work with Webstrates (webstrates.net), our web-based platform for malleable and collaborative software. With SpatialStrates, we now extend these ideas into the third dimension.
In fact, I presented Webstrates exactly 10 years ago at UIST 2015 in Charlotte.

These shared spaces can of course also be viewed and interacted with through a 2D representation.

In practice, this means you and a colleague can work in each your own digital room, with your own tools and objects, while keeping a shared space on, say, your desk where you can drop in objects.

Spatial transclusion allows spaces to be embedded within other spaces. If you know HTML, you can think of it partly like an iframe in space, a space inside a space, and partly like a shared Dropbox folder, where everything inside stays synchronized between those who share it.

For example, users can interact with objects on a digital whiteboard (think of Miro). But this board is in fact a projection of objects in a 3D space, allowing the objects to be viewed and interacted with seamlessly in immersive AR or VR as well.

To make this possible, Spatialstrates builds on two simple but powerful mechanisms: projection planes and spatial transclusion.
Projection planes map between 2D and 3D, enabling collaboration across realities so to say.

In Spatialstrates, users can interact collaboratively with digital content spatially whether it’s simple digital post-its, 3D objects, or interactive data visualisation pipelines as we illustrate in the paper.

Spatialstrates is a web-based platform for collaborative cross-reality computing. In practice, this means software that people can use together, simultaneously, whether they are on a conventional 2D screen on a laptop or inside an immersive 3D environment using a headset.
