I hacked up something similar the other day with Smoothie Charts: http://kedge.loggly.com/. I was inspired by Hummingbird though - glad to see it working again!
This looks awesome, but is unusable on my Quadro FX 380 in Linux - X spikes to 100% and my entire machine (despite being a Xeon + 16G + SSD) lags incredibly.
Checked with a colleague and it works fine for them however, must be a bug in my setup of some description.
