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).
