Works really well on Linux Mint. Needed a good gray theme so it melds with the top gray bar that you get on Linux.

I like the theme of the 'African Grey' because of the picture of course. It's like people not every 'African Grey' have the same looks, but I like this one because it's near ours. We have two and love them as our children. It's a pity that I can't change her/his place, because of the add-on icons and tabs under it (that corner is pretty full)... With the fact of the last paragraph I give you 4 stars. Hope you can push the picture a little higher (for me). The grey background colour of the theme is okay for me because it gives a soft transition to the outlines of the parrot, it's a lot better as the hard shade of colours of some other themes (to get pain in my eyes).
