The Spotstock site was used to promote a week-long virtual festival that I put on for my friends. The site is (at the time of writing) running at http://spotstock.heroku.com.
If you want to make this run, you'll need to add bit.ly credentials to admin_controller and probably uncomment the admin route in routes.rb.
Spotstock was written on Friday for a festival that began on the Monday. It is a simple site with no tests and it is mostly static. I know that the bit.ly credentials should be in a config file. Sorry.
