Visionect have a 32" ePaper displays in color and grayscale: https://www.visionect.com/blog/32-inch-eink-development-kit-...

But they're pricy: grayscale is $3600, color is $4700: https://www.visionect.com/development_kits

The underlying display is still made by eInk Inc, who sells a very similar product on their own website: 31.5" instead of 32", and only in grayscale - but surprisingly: for only $2000: http://shopkits.eink.com/product/signage-evaluation-kit-v3-w...

I plan to buy one of these large eInk/ePaper displays and mount them on the wall in my home's atrium where I'll display a dashboard showing traffic levels, road cameras, and a weather update. I'd really like color though, but $2000 vs $4700 - I guess I'll make-do.
