It has been a while coming but it is very nice; a new free Joomla theme and if I'm not mistaken there are another two free ones you can download from here too!Each one of these free themes is XHTML 1.0 Transitional Valid, have fully collapsible module positions and work with all the browsers. Oh, did I forget to mention that they're actually very nice too, I particularly like the one that you are seeing in the thumbnail, it's called New Horizon.
It is a drak but colourful theme if you know what I mean and has a rainbow on a dark background. It reminds me of a RockeTheme theme but just doesn't come with all the bells and whistles that you get with RocketTheme.
Which isn't actually a bad thing. Sometimes you want something simple and I'm not saying this is simple but it is very clean, fast loading and looks very professional.
I think I might be using it myself! So, for a demo of any of the three themes ro more information click here.
