The talk of bitsy's limitations reminds me of the tools where I learned super-small scall (and sometimes monochrome) pixel art... the Etch-a-Sketch animator.
Brilliant piece of tech for the day: a Gameboy-ish screen (but with FAT pixels, 40x30) and a digitized, screechy version of the traditional etch-a-sketch dials (heh, shake to erase was still a decade or two out for digital stuff), and 12 screens that could be played back in sequences of over 100 frames
I reproduced the examples in the booklet here: https://kirk.is/features/etcha/ and this is another art-minded thing I did: https://kirk.is/2002/04/15/ (I'm kind of intrigued with "photorealistic" stuff on super primitive display systems)
The biggest connection was me making tiny tiny fonts, 3x4 and what not.
Anyway, anyone here use either of those?
