Kinda slipping off subject
Those huge LED video walls you see at concerts and other events? They sure look nice when they are working. They go up in panels that clip together. The maintenance to get them going 100% can be mind blowing. Always working on them to the last minute. Constantly panels going out. Replacing them after its setup is a true PITA.
Point being, the technology is awesome, but very fragile, even when made to be road worthy. In other words, look, but don’t touch.
