Ubuntu jaunty new login screen - awesome!

Take a look at the Ubuntu Jaunty (Alpha 6) login screen. These look perfect and professional! (Click on the images to see these enlarged)

















These images are from the Jaunty Alpha 6 running as a VM on QEMU emulator.
On a side note, I was surprised that a sound device was detected on the virtual machine, which never was detected on my previous virtual machine images running on QEMU...but no sound yet..:(..Need to check what is going on !
