This animated ANSI .NFO file was released in the Blocktronics "Detention Block AA-23" artpack. Code by Kirkman (Josh Renaud).
If you'd like to read about the creation of this animation, read my 2017 blog post "New ANSImation: Star Wars opening crawl".
This animation runs in Synchronet BBS software's Javascript environment, and requires its Frame.js and Sprite.js libraries. It also uses the perspective-transform.js library to skew the text of the opening crawl.
The code in this repository can be switched to output one of several crawls: Star Wars, Star Trek, and the Blocktronics pack.
You can also download the animation in ANS format.
