Colours to decorate machines

Hello all, long long time ago (I don’t if it was on elektron-users) I remember a post where all dudes were showing their machines and how they decoreted them with any possibile tool.
There were plates, stickers and this particular guy who was showing this sort of extruded fluo colorful decoration on his machines.
It was quite intense as decoration and quite “tridimensional”… It wasn’t a 3d pen like the many available now. It was a sort of pen (like uniposca) that was like an expanded foam.
I’m sorry if I cannot explain it better (if I was able maybe Google understood me)… But if there is anybody who knowssl what I mean or remembers this old thread… Any help is much appreciated.
Thanks a lot!

I maybe found something about the type of paint used (puffy paint?), but I am still searching that thread…it was really nice
