I would love a standardized way to render a simple pixel framebuffer in terminal windows that's fast enough to update at display refresh rate. The current solutions I tried (like Sixels, or iTerm2's imgcat) are good for rendering static images, but not for realtime updates.

This would allow me integrate actual graphics into my "C64 emulator for docker" instead of just a subset of the PETSCI character set :)
