Here is my (very red) theme, which, whilst it may not be the best theme ever, is the first theme where I have changed the images, not the gtkrc file. It is a very heavily modified version of sen7's mira v2 theme (located here: http://sen7.deviantart.com/art/Mira-100077120). The screenshot here does not really do it justice, so there is a beter quality png screenshot in the download. Though, hopefully, the screenshot here is enough to show you whether you like or dislike it. Anyway, hopefully some people like it, and constructive criticism is welcomed.
