This is insanely cool, the noise they make is also really satisfying!
What was the cost/time breakdown of the entire project because the flipdisc prices are hidden behind quotes and it seems like it would take quite a lot of time to complete the whole display!
The prices I’ve seen mentioned are around USD$3-5 per “pixel”.
Similar to all the ePaper projects that show up here, they’re expensive but cool gimmicks.
