This morning I was thinking of porting the screenlets code from Pygtk to wxPython, this would make a widget engine for the three main Operating Systems, four if the porting is made to
pygame.renpy.org/ Pygame for Android or
ignifuga.org/ .
The code isn't really much and being Python it's fairly easy to port, yet I would need collaborators, especially people with better programming skills than mine.
