Designing your first animated display can be complex if you aren't already familiar with how these things work. It really depends on what precisely you are looking for. We carry chase controllers (just movement, no music), we carry an automated sound to light controller for AC lighting (The Music Box) and we carry an AI based app controlled lighting system for RGB lights (Twinkly/Twinkly Music) - but we do not carry any of the systems that the pros use to create those fancy synchronized light shows you see on Youtube - those are very very complex.
Most folks who are just getting started with adding motion to their displays will start with the chase controllers and not try to synchronize the sound at first. Or they will use chase controllers for the most part and then build one prop that uses an AI technology to create a synchronized light show.
