Drawing with Bones
PETSCII is the Commodore character set: not just letters and digits but a full kit of box-drawing pieces, diagonals, shades and blobs, baked into the ROM of every PET, VIC-20 and C64. Artists turned that kit into a medium.
The palette is the point
You get 16 colours and a grid. That is the entire toolbox, and it is enough:

Switch the font in the top bar to Commodore 64 (PETSCII) and the page re-renders in the genuine C64 ROM font — every glyph cell-aligned, exactly as it looked on a 1084 monitor. The ANSI renderer (and the effect box below) use that same selected font, so your art and your text stay pixel-true.
Embers
Here is the framework's fire effect chewing on some text — set the font to C64
or Atari first for the full séance:
Where to go next
The scene archive at 16colo.rs holds decades of PETSCII and ANSI packs. Study the masters, then open a grid and sign the bottom-right corner like you mean it.
