Using bash I made a text "animation" of nyan cat. The 2nd link on google for "nyan cat ascii" led me here:
http://evilzone.org/creative-arts/nyan-cat-ascii/Kudos to 10n1z3d
I added option for music in it, using either vlc or mplayer. Those lines are commented by default. Tested only with mplayer, but vlc should work.
Was made mostly as template for this type of thing. Wasted a good hour doing this.
Example Output:
#!/bin/bash
# config
