Few simulation zones work together to draw a mask from curves

There are two parts to this: first part takes collections of curves as input and outputs values, second generates board geometry and uses output of first to generate mask  
Both parts use simulation zones, whole setup is quite modular - its possible to add more collections/“chalks”, it also works with any 3D curves

First idea for a render was to just draw a standard Blender logo, put some basic school-y on board, desk next to board - it was rather bland, then a little side track - how can i get an flat outline from any 3D object, ive managed to get it work with another camera, a plane, grease pencil’s line art modifier and some more geometry nodes, I’ve imported Blender logo from .svg, extruded it a bit a then put on a board

That outline wasnt enough though, project was put on hold for week or two, then i got another idea - take that outline and just blast UI icons from Blender itself all around it

All icons were downloaded from [https://ui.blender.org/icons](https://ui.blender.org/icons), imported from .svg files as curves, then split more or less equally into three collections  
At the very end i’ve added some basic camera movement, lightning and compositing  
Didnt noticed animated sensor noise was that noticable until it was done rendering

Cabinet, notebook and pen holder from interniq

WOW !  
The animation is cool !!  
The chalk dust on the blackboard looks also good.

I thought a variation in line thickness and transparency,  
like you get when drawing with chalk on a blackboard,  
would also be nice.

But pretty well done !
