This ANSI art animation was released in the Blocktronics "Detention Block AA-23" artpack. Artwork and code by Kirkman (Josh Renaud).
If you'd like to read about the creation of this animation, read my 2017 blog post "New parallax ANSImation: Millennium Falcon dodging asteroids".
This animation runs in Synchronet BBS software's Javascript environment, and requires its Frame.js and Sprite.js libraries.
You can also download the animation in ANS format.
(The code in this repository and the animated GIF above fix a couple small rendering bugs that were present in the artpack release)
