I wrote this little program to be able to easily create mp3 sticks to play in my car directly from my Amarok collection). For this purpose the stick needs a flat folder structure and be sorted alphabetically before copying.
The small Qt4 dialog has a drop area where you can drag mp3s (from file manager or Amarok, perhaps also other programs) onto it and it will read the ID3 tags and create a sorted folder structure with "Artist - Album" and shows the number of tracks and size it would take....
Create a server for 3D worlds similar to opensim with python and postgres, the goal ist to have a small and fast implemetation. Also to build a viewer working in a browser.
