A modified version of Gruber Darker with pink accent instead of yellow.
First, choose a directory where you want to store your themes, then add the path to the chosen directory to custom-theme-load-path by adding this to your init.el/.emacs:
(add-to-list 'custom-theme-load-path "<your themes directory>")
Then you can just download groover-darker-theme.el into the directory you've chosen.
