This was a really interesting project, consisted on grabbing information from multiple sources, and plot temperature maps to show warmer areas in the computing room. The design was originally thought as an iPhone application, but it was developed as a webpage to allow the use of a wider spectrum of clients.
Next are snapshots of the menu system and actual visualization:
The highly configurable interface allows to plot different maps and overlays. The next two show the UPS and computing rooms.
Using historic data from RRD Databases it's also possible to generate informative movies (they are generated for PC or mobile device, the example corresponds to a mobile device)
It is also possible to see who's actually in the computing room using webcam screenshots:
Also, using those screenshots it was possible to acquire and store videos using motion detection:
