The power monitoring thing is something we created internally. It uses current clamps and Arduinos to push data into a web service. You're right that the graph is more pretty than functional, but it wasn't intended for wall-size display. Most people access it on their desktop and it's quite legible in that context, and it just seemed a handy thing to stick up on the status screen.
There's some more background to the power monitoring stuff here: http://www.practicalarduino.com/news/id/441
How much did the power monitoring cost?
Also, the background on the graph makes it practically unreadable. You should consider bright lines on a black background.
