CI-Eye is a powerful continuous integration build radiator requiring no installation and almost no set-up. CI-Eye talks to many different CI servers through their REST APIs (so no plug-ins are required). Currently, support is offered for Hudson, Jenkins, and TeamCity. CI-Eye runs as a standalone Web application.
We use Ci-Eye extensively at work to drive our build radiators, and it is very easy to set up and maintain.
When we added our developer pictures, it had an immediate effect on the number of failed builds. Turns out people pay more attention when their picture is on a red build.
