I did mention earlier I will be putting together a .blend which includes all the quick shaders I have been doing for a while (twitter moment here, link should still work but I can't update that anymore, sadly) so here it is.
Edit1: To make it simpler(and also less messy, at least for files with incremental updates like this) I will be updating this post for any new materials added to the file instead of making new post(s).
Edit2: Looks like the twitter moment thing is finally dead so everything is gone(technically, can still find them but it's a little time-consuming), but most of the content can still be found on this youtube playlist. A note that a lot of the shapes are simplified setups of sdfs but it might be better to use an actual sdf depends on your use case(i.e. 2d sdf nodegroups here)
v100: added stylized flame, file now created using 3.3.20
