Since the iPhone tocuhscreen is quite small and has great support for interactivity a 3D tag cloud looks an ideal choice for an iPhone application user interface. Neither iPhone SDK classes nor 3rd party libraries have 3D tag cloud classes, at least no libraries I heard of, so I implemented it from scratch.
You can see the final result in the Toneaphone Ringtones iPhone App we developed last year.

One of our projects currently under development is a 3D puzzle game where player will manipulate a number of cubic blocks. Those blocks can be moved above the board so to look realistic they need to cast shadows onto the board. Despite shadows are used in many 3D games and OpenGL ES does have all necessary things to implement them there is no support for shadows in API itself so the implementation is not straightforward at all. The task requires some smart coding. Let’s see how it can be done.
Toneaphone is one of the greatest and most unique mobile media companies you’ll find out there.
