[Phys-L] Visualizing electric fields and potentials

I just wanted to share a recent (re-)discovery for the macOS users out there. For many years I used a piece of software called “Franklin” for classroom demos and the like. It did a wonderful job of visualizing electric potentials and fields in 3D, and is highly configurable. Like many pieces of educational science software (Atom in a Box, anyone?), I was sad to leave it behind when I moved all my machines to Catalina. But I just recently discovered that the developer has released a 64-bit version of Franklin that runs fine on Catalina:
