Here are some scripts I wrote to generate ascii art patterns.
To get a list of options, run the scripts with the -h or --help switch.
Here is a script which converts simple vt (ANSI) animations to javascript. It only works on the ones of the form: [frame] [newline] [escape code] [newline] where [frame] contains only ascii 32-126
Following a discussion on alt.ascii-art about detecting ascii-art with a program, I wrote this script which is a very basic attempt. I have tried to make it easy to add new detection rules and alter the weightings for each rule, so it can be improved.
