Hey guys not a big post or anything but I thought I would share. Being a *nix user, one of the things I miss from windowz and macs are the virtual desktops. I found this tool online that you can use to emulate that exact thing.
Desktop Manager for OSX
Using this, you can quickly shift your entire desktop back to work using a keyboard shortcut or a quick mouse movement. The benefit of this over, lets say "show desktop" or Command+H is that it looks a little less suspicious and lets you hide multiple windows art once (e.x. WoW, wowecon, mmowned, the midget porn kelat just sent you, etc) This makes it easier to hide wow from your parole officer or whoever you wish to bugger off.
Combine this tool with a quick icon replacement (I like to replace my WoW.app icon with the icon from Calc.app myself) and your home free
Screeny Shots:
of course, all this visual effect mumbo jumbo can be disabled and the application runs absolutely invisible to the nekkid eye, only your keyboard shortcut will restore the other desktop
Good Luck!
Edit: Doh, wrong program section. I've asked a mod to move this. Sorry.
