Its great to see that continuous integration acceptance is growing. Sismo is the CI system created by the symfony team for monitoring symfony itself. It is written in symfony and will be open sourced.
When I first saw it, I was not happy about it. Mainly because it is “yet another tool”. But what I do like is to look at it. Its the most beautiful CI frontend I know. You might argue that being beautiful does not matter for a software development tool, but I tend to disagree. It just makes it more pleasant to work with it.

Chapeau, Sensio designers. I really like your designs. I think the symfony components website, which just had the third component launched, is one of the most appealing framework/library sites I have seen so far.
