Not sure if there is the right place to post this but...
http://img.files-ds-scene.net/news/woopsi024b.jpgWoopsi is a BSD-licenced windowing system for the Nintendo DS, written in C++. The aim of the project is to create a simple windowing system that programmers can use for their applications, decreasing the tedious amount of GUI code that people have to write.
The system itself is loosely based on the Commodore Amiga’s “Intuition” windowing system. Everything in the system is treated as a “gadget” (in the same way that Windows treats everything as a sub-class of a window), everything takes place within a “screen” environment, and the look-and-feel of the system intentionally resembles the old Amiga system.
The windowing system is *not* intended to be a complete desktop environment. It is *not* going to be a DS version of GNOME, KDE or Windows Explorer. It will simply provide a system for rapidly building window and gadget-based interfaces.
