FAQ
It looks kind of low-resolution and crappy
Thanks! That's not a question though. The resolution is limited
to the number of columns on the terminal and twice the number of
rows. Vertical resolution is doubled by using the half-block
character "▄" (U+2584), so an old-school 80 column, 24 row terminal
window is effectively a measely 80x48 pixels. You can increase
the resolution by shrinking the font in the terminal window.
