Best desktop environment for Mini2440?

Hello,

I searched a long time for a good GUI like this one from Qtopia. The
problem is, that I can't find the source of the Qtopia WITH desktop
environment anymore. Only the libraries...

Can somebody please tell me, where I can find the Qtopia desktop sources or
which desktop environment is the best one (memory, speed, configuration)
for Mini2440? Thanks!

PS: I already tried the prebuild Qtopia from here, IceWM (also a good one)
and OpenBox.

Maybe GPE: http://labs.kernelconcepts.de/Projects/Micro2440-Mini2440/

Thank you for the link! GPE seems to be a good desktop environment for
mini2440.

Is there any way to install GPE separately, for example on debian? Or do I
have to use Openembedded and Angström, as used in the image?

GPE is available under debian linux for armel processors too. You can
install it via APT. But as far as I know that version only works with
X.Org...
