Skippy 0.5.0 Description:
Skippy is what (I think) is best described as a full-screen task-switcher for X11. The project tries to provide an alternative when taskbars or regular task-switchers aren't the most efficient way of switching tasks (like when you have a lot of applications open). When activated (currently only through a hotkey), it will arrange and scale snapshots of all windows on the current desktop and it'll let you pick a window using a mouse or a keyboard. Yes, this is also what expocity and Apple's Expose do (yeah, I know, Expose does more than just this), but I don't like metacity (expocity is a 'hacked up' version of that) and I don't have a Mac.
