I like to noodle about making GIFs. Many are going to be from Invader Zim.
You are free to link to them or copy them. But I would prefer that you link, because The Internet Works That Way.
If you have any requests, then feel free to ask me via twitter. I might even honour the request one day. Or, if you know how and can be bothered, issue a pull request with the suggested configuration for a new GIF.
The GIFs are all created using FFmpeg and some python to create captions.
The site is generated by flourish, uploaded to and hosted from, Amazon S3.
The source and more information can be found on GitHub.
