Extend Customizability

Customizable Light Source, a desktop-based media player (cool if a 3d radio can be shown) which of course, should also be customizable, Multiple floor levels (for very, very deep desktops) it would be a good idea to add some stairs/elevators for changing floor levels. Consider also adding customizable velocity/speed of items. This would look cool if items could "bump" to the wall while moving on its own. New customizable icons can also be implemented like instead of using the "old fashioned" 2D picture in 3D space, why not add a feature for replacing 2D icons with 3D ones for every item. In that way, it will add more depth to the environment. If possible, 3D particle systems could also be implemented for creating customizable particle generators for smoke, water flow, etc. This would add great effects for the aforementioned 3D icons. For example, a 3D train icon which would move in a given route (as can be customized), with its customized speed could, at the same time emit smoke.
