Aloha from Germany!
I just discovered that the Divoom Pixoo frame, a cheap 16×16 pixel display, has an app in the Google Play Store which has a LOT of interesting/good animations from users. The app can export in animated GIF – not in 16×16 but in a 384×384 format that can be rendered down to 16×16 with the converter tool available for Gameframe. The app does NOT require a Pixoo and needs simple registration which can be done with a throw-away Email.
While it is sad that nothing more seems to happen directly with Gameframe, I just downloaded about a hundred really good new animations to it thank to this new source of GIFs.
The app can be found here:

All the best,
