Aqua-Soft ForumsI quickly altered the colour of the default skin for RK Launcher to, what could be called, quite simply, dark glass. The only change is the colour, for those of us who appreciate the original look but would like it... just a tad darker.
I take no credit for this as my alterations could've been done by a turkey with half a brain.
However, I do hope you appreciate my saving you clicking that Photoshop icon. Oh, the potential strain on your fingers! 
The zip includes backup theme PNG's in case you lose the originals like a crazy fool.
I heartily request that, as with all .ZIP files, you virus-scan it before you open it. Can never be too careful.
I'm using it with RocketDock, no RK,
