Finally got some more time this week, started making a frame to mount the projectors and other bits. I'm hoping that by the end of the week I'll have something functional, and if that goes well the next step will be making the cosmetic parts like reflectors and lenses, as well as some finish panels for the top most likely.
This isn't my only project, so progress will be sporadic, but I've got an event next weekend, I'd love to have working lights for that.
