Starting to (sort of) answer some of my own questions. I’ve found popspin and enabled Uniform Scale with a VEX of pscale *= rand(@id); 

Need to read up on rand, I assume I can do something like rand(0,1) to define a range

The kind of thing I can do in Maya and Mash pretty easily but seems like something I should be able to tackle in houdini. I’ve figured out the emitter flowing along paths, and finally figured out that I also needed to add a instance thing underneath the import_location (why is that, btw?) because my popinstance would show up in the scene but not render. That took a while.
