Blue Turtle HB is David's and Filip's venture for music and programming projects. We also do consulting work. These are some of our current and past projets:
David is about to release a new album called 'Voyage to the unknown'. 
The Game 'Cyber Warrior' is about to become. A 3d game staring a warrior in huge armor shooting cows and sheep... 
Filip joined a project to build an Open Source membership database (site in Swedish). The project stalled due to lack of interest from the would-be users (they decided on a commercial offering). If there are prospective users however, we would be happy to take the stuff forward.
