Was just playing with Lua last night and came up with this--setup for Gnome3 and 4 CPUs. Feel free to mod this to your liking--change it if you want--just credit me if you use some of it.
Edit: Just changed things up a bit & added graphs for 6 CPU. Includes scripts & needed font...just drop them into your /home folder & ENJOY!!!
I still wasn't happy with the 6 cpu look, so I changed it up a bit more. Please comment which you like more & if you want the 4 cpu version to look the same. ENJOY!!!
