Ok, I am new here, and to the light animation world. I am excited about getting started, but I am on a budget and need to start small. I plan on getting in on the coop, and am wondering what else do I need to get a show up and running. I know I need a computer, with software. Got that. I am planning on ordering at least 2 LE's, what does the wireless do? Do I need a dongle? Starting from scratch is exciting, building from ground up. Thank you in advance. I am so ready to build!!
