John and Jon are in St. Louis again with a new open-air booth that customers are finding more inviting -- turns out we didn't need the bat cave to demonstrate lighting effects.

The "Stranger Things" demo is a big hit. We used an HC-8+, and Android app that I put together using MIT App Inventor, and some RGB Christmas lights from HolidayCoro.com.

If you're in St. Louis, stop by and say "Hello!"
