SmartFlip 0.8 Beta 2
SmartFlip is a replacement for the Flip3D function in Windows Vista. It places the windows on a circle (it’s actually a ellipsis combined with a parabola).
You can select to which window you want to flip by using the keyboard or the mouse. You can use as a trigger a keyboard key (you can even replace Flip3D, so that SmartFlip appears when you press Win+TAB) or a screen region (for example, the left corner).
