I loved smith charts during my microwave classes in college. I've always felt like there should be a fun game based on the mechanics of using a smith chart.

This software is so good it is as enjoyable as any game, it taught me to love Smith Charts

I’m just amazed there isn’t a nearly impenetrable Greg Egan book based on them.

If you liked the Smith Chart, you'd love using the Spirule to solve root locus problems.

I felt the same way. At some point shortly after graduation, I found a heavy plastic Smith chart that was designed to be written on with a grease pencil, and erased with a cloth when you're done.
