Ultra slow, 2 colour, low resolution display panel with sub-optimal refresh rates.
I saw this

and thought I had to have my own low-tech pixel display.
My version uses even less electricity as you have to switch the pixels by hand.
It prints in one piece, start with one colour for the first 3 or 4 layers and then switch to the other colour for the rest of the print.
I takes about 4 minutes per pixel, so this one takes about 4 hours to print.
Let me know if you'd like one with more or less pixels and I'll upload it!
