I have seen an amazing thing.
Last year, when I went to OSCON, I met Miguel de Icaza (the GNOME master). During OSCON, he had a keynote address about the new generation of GNOME technology..and it involved wobbly windows. I saw it and I couldn't !@#$!#@ believe it. I have been waiting and waiting to put this on merman (my computer's name...my laptop's name is trapjaw).
You have to see it...here and here.
Vista, eat your heart out.
