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.

		Whole dollars per pixel is insane! The whole mechanism looks very 3d printable... I wonder if one could design one with PCB coils and a large 3d print only? If so, cost could probably come down to cents per pixel... You'd probably also need a single 'C' shaped piece of steel for the magnetic flux path, but you might be able to find a supplier for the right shape already used for something else you can buy in large quantities very cheaply (eg. Steel staples).
