Used Novell images - hope there is no licensing issues.
I got tired of using the same boring Windows 7 themes so when I found these cool graphics files for Geeko creatures on Novell's web site I created a themepack using them. I also created a new login splash screen using one of them using a free tool called tweakslogon which I found on the net.
