Apparently Real Desktop Light is just a program to convert desktop icons to 3D, making them much more spectacular, especially some specific icons.
But Real Desktop Light has much more to offer, as in addition to adding this 3D effect, you can also play with those icons, by making them bounce from side to side on the desktop, rotating them or smashing them into each other.
Certainly a curious way to get more out of the static icons on your desktop. Also remember that Real Desktop Light hardly consumes resources, and while your icons are resting on your desktop, there is no affect on the PC's efficiency.
NOTE: For Real Desktop Light to work correctly you need to first install DirectX 9.0 or later.
