Inspired by a (non-)challenge from Patrick Lichty to create a bot to create a daily image based on the work of On Kawara's "Today" series. Patrick has his own site where he does the same. The original proposal was to post to flickr, so I may extend it to do that (and more!) soon.
You basically just need to edit keys.pl with your own twitter API key values. Then maybe set
up a cronjob to do this daily.
Also included a bonus svg which does roughly the same thing and an example of it embedded.
