Entbloess allows you to see live previews of all your open windows in a manner similar to Apple Expose. It also supports mouse interaction, complete customization, and animation. It can be executed via a single keystroke or mouse hot spot and supports operating by either mouse or keyboard. Entbloess allows you to see all windows, or only windows from the current application depending on which key you press (or which hot spot you use).
