Qt based desktop, featuring AnticoDeluxe
A friend of mine told me about his idea for making a whole Qt based desktop with many Qt applications.
The idea is described in his page here : http://code.google.com/p/semen/wiki/QtDesktop. What is very good, and you may notice it, he aims to use AnticoDeluxe as Desktop Environment. Of course, not all (even none) of the applications match the overal look & feel of AnticoDeluxe, but they can be patched a little and become very integrated into AnticoDeluxe.
