Audiotube's work will never be done, as there are thousands upon thousands of songs to pick and choose from; that's why we'll need you to give suggestions for future additions.
Surge needs problem generator files, and while there are a significant number of those written already, they are somewhat disorganized, so you'll be seeing those posted in the near future.
In the meantime, VB Gadgets has a question for you: for a future project to be developed, would you like to see this:
Windows Explorer 3D
Windows Explorer 3D would provide the same functionality as your traditional Windows Explorer program (what people think of as "My Computer"), but would have a 3D viewing capability. Files and folders could be displayed in "Cube", "Amphitheater", or "Sphere" mode. This would be a fairly large project, as even just making an imitation Explorer program would be daunting.
If you like this idea, what could be done to this program to extend its usefulness beyond that of Windows Explorer (tabbed browsing, anyone)? A quick Google search didn't turn up much concerning this kind of a program; most projects took things to a whole new level by remaking the Windows shell (what you see everywhere: the start button, the taskbar, etc).
