My prompt is five lines tall, including three blank lines. I did that, along with some bright green coloring, to make the prompt easier to spot as I rapidly scroll up through a mountain of output from my last command.

zsh prompt:

PROMPT='

%{$prompt_default_color%} %~ %* %{${fg[$prompt_user]}%}%n%{$prompt_default_color%}@%{${fg[$prompt_host]}%}%M%{$prompt_default_color%} ${vcs_info_msg_0_}_

$ %{${fg[default]}%}'
