Feel free to leave comments here regarding IrishPulse.
Here is the source code, as diffs from the current bzr version of Venus (as of 2008-03-06):
http://taint.org/x/2008/venus-20080306-add-title-to-feed-id.patch - a very small patch to fix a lack of uniqueness in Twitter's Atom feeds; all feeds from Twitter use an <id> of "tag:twitter.com:Statuses", which results in Venus ignoring all but one. This is a patch against Venus.
http://taint.org/x/2008/venus-20080306-read-face-attr-from-opml.patch - a rather more hacky patch to read the face data from a new, nonstandard "face" attribute in the OPML.
http://taint.org/x/2008/venus-irishpulse-theme/ - the Venus theme.
http://taint.org/x/2008/twitter-followers-to-opml.txt - a perl script to download a list of a Twitter user's "followers", and generate an OPML file with the results. Net::Twitter is required, and you also need to create a ~/.twitter.cf file containing:
$user = "twitterusername"; $pass = "SomePassword";
http://taint.org/x/2008/detwitter.py - "filters/detwitter.py", modifies the Twitter messages in the feeds to add some useful markup and remove some extraneous noise. Use "filters = detwitter.py" in the Venus config.ini.
