Last time me and makefu were amazed by how good the ledbar turned out and built some/are in the process of building 50 linkable rgbboxes. https://github.com/excogitation/rgbcubes Maybe someone from the ledbar hackers is at brmlab later to talk to?
Ooh, that's pretty! Great work there. We had some similar ideas in the early stages of the project (converting it to a kit form and having a build-at-home version), unfortunately we never had the time and dedication to pull it through. BTW, is this your target brightness or do you plan to use some higher-luminosity LEDs for next iterations?
Note that when you have many high-current LEDs connected to the same PSU and shared bus and the lines are several meters long, you *may* start hitting AC interference etc. issues if you didn't design your bus properly; that happenned to us in the first version of ledbar. Just something to keep in mind as you scale things up.
Making the cubes individually controlled and IOT is also an excellent idea - it wasn't a good fit for ledbar, but two guys at our hackerspace (TomSuch & da3m0n22) built essentially a platform for exactly that, including an Android control app etc. Maybe you catch them in the space tonight, or you can ask others for "MoodyLight" and there likely are some prototypes lying around in the hackerspace. It might be nice to join forces.
