I just got a little server together to serve up the data that my sensor logger is collecting. The Google chart API makes it very easy to create a fancy zoomable time-series chart (link goes to Google documentation as my server is not accessible to the outside world).
The code is all on my github at https://github.com/fasaxc/WirelessSensorNodeServer. It's not much good without a serial-connected Arduino piping it data, I'm afraid! However, it does show how to put together a minimal tornado server in a virtualenv that can serve up static content and a RESTful JSON API.

The electronics are based on a project by one of my colleagues. It all fits in a laser cut enclosure that I designed.

I just posted a new instructable detailing how I made the box in the picture. It all started out as a flat piece of cedar plywood!
