Load this as your terminal's start screen

Static image

1. Generate your art above. Turn off color — plain cat prints raw text, not the colored HTML this tool renders in-page, so a color-mode export will just show literal <span> tags in a terminal.
2. Keep width under your terminal's column count (usually 80) so lines don't wrap and distort the art. Check yours with tput cols.
3. Click Download .txt and save it somewhere permanent, e.g. ~/.ascii-art.txt.
4. Add one line to your shell's startup file so it prints on every new terminal:

   echo 'cat ~/.ascii-art.txt' >> ~/.bashrc   # bash
   echo 'cat ~/.ascii-art.txt' >> ~/.zshrc    # zsh
   echo 'cat ~/.ascii-art.txt' >> ~/.config/fish/config.fish   # fish

5. Open a new terminal window (or run source ~/.bashrc) to see it.

Animated GIF

1. Drop a GIF above — it starts looping in the preview automatically. Adjust width (keep it under your terminal's column count — check with tput cols) and the other controls until it looks right; color works here, unlike the static path, since the export uses real ANSI escape codes instead of HTML.
2. Click Download animation script (shows up once a GIF is loaded). It bakes every frame's timing and pixels into one self-contained .sh file — nothing calls back to this page.
3. Save it somewhere permanent and make it executable:

   chmod +x ~/ascii-animation.sh

4. Add it to your shell's startup file so it plays once on every new terminal:

   echo '~/ascii-animation.sh' >> ~/.bashrc   # bash
   echo '~/ascii-animation.sh' >> ~/.zshrc    # zsh

5. Open a new terminal to watch it play through.

The script plays once and exits back to your prompt — it won't hang your shell on every login. Want it to loop forever instead? Open the downloaded file and wrap its for loop in while true; do … done.
