Reddit user /u/Ridley126 made one 16×16 pixel artwork everyday in 2015.
I think these are perfect for the gameframe. I applied some scripting magic and brought them into the gameframe format. The attachment contains a version with single images and one with all frames in one bmp file.
Since I built my LED matrix with a Raspberry Pi and wrote the software myself, I can’t check if they are in the correct format (please confirm if they work for you).
Also, I think it would be great if they could be played in random order or even in a “calender mode”. I think I’ll do something like this on my hardware.
Thanks to /u/Ridley126 !
