Zwe is a weblog and website engine created by Maxime Petazzoni. The latest version, v2.6-angela has not officially been released but is recommended for production use.
A few people actually use Zwe as their main blog engine. If you want to see what it looks like, I am using it since its creation for my blog. There is also a test instance setup here if you want to try it. The development website also host some valuable information and documentation.
Zwe is currently under heavy redesign and redevelopment. Please see this page for more details.
