Show HN: I added a photo gallery to my e-paper smart display
I keep iterating on my e-paper smart display. It's still a side project I am working on after work. I think it has come a long way since I first posted about the idea here on HN - and I plan to keep going with it!
My newest addition is a photo gallery app for the display!

Users can upload pictures from their smartphone and show them in random rotation! The photos are converted to black and white, using dithering to achieve the illusion of grayscales.

Interestingly, since this is a photo of a display with a dithered image, depending on which computer screen this is displayed, it can look like they are patterns in the dithering which aren't visible in reality!
I've been thinking of adding remote upload to my inky-impression fork https://github.com/KodeMunkie/inky-impression-slideshow
Performance isn't great being Python on a Pi, but would be a heck of a lot quicker if the dither had an option of being JS and client side instead of Python. It could then store the data in a bit bang/raw RGB format suitable for just dumping to the display via Python.
