This sculpture is complete but I wanted to add some logs on how I got from the idea in my head to the final design.  I've had the idea of making a sculpture using current limiting resistors to mix colors for a few years now.  Below are some pictures of my first attempts.

1st attempt in March of 2020.  I had a few hundred 10mm RGB LEDs that were for a project that was canceled due to the pandemic on hand so I decided to start adding them to a piece of wood I had whose shape I liked.
