This program brings you a 3D cube which will be used to switch/rotate between running programs.
This will be useful if you assign a hardware button to it.Currently program dont do that automatically!
Use Settings->Personal->Buttons to do that.(assign it to '3D AltTab Switcher').
You can also customize your animation effects from settings,and also animation speed.
If program doesnt show animation either you are low on memory or you have to manually assign a Graphic engine(like GAPI or DirectX) to program.(from settings)
