How to use:
Place downloaded file 'default.dll' in either:
for Vista - C:\Users\USERNAME\AppData\Local\Google\Chrome\Application\0.2.149.27\Themes
for XP - C:\Documents and Settings\USERNAME\LocalSettings\AppData\Google\Chrome\Application\0.2.149.27\Themes
(You might want to backup the original 'default.dll' first)
Edit 080910. Zombre dark has become Zombre - 'cause it looked so much better. So there's only one version now.
