Honestly, I think a real "pin display" like this would be really fking cool irl (of course the back can't be open since there would need to be a mechanism to move the pins) It's not practical for anything with color, but stuff you can put on an LCD (clock, alarms, text, etc) would work really well. Plus the fact that you can physically display depth might have some uses too. Maybe if the pins were a bit longer you could display terrain maps and stuff on them, or (simple) waves and such. Would be pretty cool. Maybe something like this exists already? Also, if you don't put a cover in front, you could have a haptic "touch" screen, or more like dynamic buttons or something. Like, the screen can generate a physical button anywhere, with any shape, and detect if you press it. Could easily put text or a logo on the button too.
i know this is 4 years late, but could you make a version with a static camera angle? it's kinda irritating every time tge camera suddenly snaps to another angle
Not really that difficult to do, specially with the geonodes, if you configure the height maps correctly any video on that display, im more impressed by how nicely it fits with the audio, i always have problems related to timing and framerates.
