Here's some live sparklines of NHibernate related projects activity over 7 days. They're updated hourly.

This all started when I decided I wanted a sparkline on nhforge.org to show recent SVN usage. Given that it's a quiet sunday, I decided to write some code to analyze an SVN repo and generate me a sparkline.
I wrote some code that runs on my server, generating a new javascript files every hour or so. It's not pretty, but does the job!
You call it like this (see the code comments)
ruby svn_analyze.rb [Project Name] [SVN public repo]
It then spits out a javascript file that you can include in any HTML page.
Porting it to c# should be easy for anyone who's interested.
