Where Can I find transparent Window themes for Gnome-shell 3.4

view story

http://askubuntu.com – I'm playing around with various shell themes, but noticed that they don't necessarily match the available window themes. I'm using the Gnome tweak (Advanced settings) tool, and am not sure how to get other options to show up under Window theme drop down in the themes section of the tool. I'm specifically looking for a way to match Frieze transparent top panel, but also the windows title bars in general. Am running Ubuntu 12.04 (HowTos)
