I recently released a full-vector visual compressor designed to help people understand compression better and to act as a fast-use plugin. IPlug’s graphics are seriously really awesome and I ended up writing my own graphic toolset for my future plugins starting with this one. One thing I’ve noticed in plugin development is that just like music producers have their own “sound”, so do plugin designers. There are a lot of companies where I could see the interface and pretty much instantly know who made it.
Here’s a screenshot of the UI - everything besides the logo in the about screen is vector:
