I don't know if it is over-engineered. They have PWMable RGB LEDs on every Nixie tube. So either use a small, cheap PIC controller per Nixie tube (for $2 each or so) or buy an expensive RGB controller.

Definately over-engineered, it says "created by John Day and Sean Cappy of Microchip" so it is no wonder they use a lot of Microchip IC's......
