It's a combination of the following:
1. Mirage.app to make the dock clear
2. TinkerTool to move the dock to the left side of the screen
3. Nerdtool to create an opaque bar
4. The dock spacers are a trick I found, but cannot remember where on the internet that was. These are the dock spacers that are not a 3rd party solution, they're provided by Dock.app itself.
5. The CPU and Fan info are scripts that are running in Nerdtool, but my setup requires the use of a special file that I don't think works on newer Macs.
I'm still running Snow Leopard on a 32bit Core Duo machine, so I have no idea if the apps I've mentioned are available for Lion.
Thanks very very much for the info!
Anyone know how I can do what Mirage.app do on Lion? Because it don't work for me on Lion..
