I see! I was thinking of using COB strips, so if you don't mind I may come up with something similar? It is a fantastic idea and will work really well with the Spaceways Parts room images on slide filmI'll almost certainly release them somehow once I've finished all of the design and tweaking. I'm not sure exactly what that will look like; whether it's files, physical prints, or via the Shapeways marketplace.
The main downside is that they're very specific to Adafruit DotStar strips and I'm not even sure if they'll work with different batches since the components and exact spacing on the strip sometimes varies.
