Realistically, that seems pretty achievable goal for a Kickstarter? Rent some smallish exhibit space (500-1000sqft old warehouse or something?) in the valley/bay area outskirts for a few months, find a large format printer service, print out in strips, and figure out physical installation. How much can that really cost? $10-20k total? Somehow I feel its not far fetched that there would be a thousand geeks willing to chip in $10-$20 bucks for this sort of thing
Japan is huge on making very large graphics from printing on sheets of white adhesive: https://youtu.be/ioyMec7YU0Y
If they added it to the ground it cheaper to install and then kids could run on it in the gym (could easily cover an entire Gym, lol):

Would be fun with the retroreflectors added like in the latter video, as with the lights off and only head lamps on you could see stars below your feet.
Imagine that in a museum, just a massive wall with 100 billion stars. It would be ridiculously cool.
