"Adium Reskinned" is more appropriate. This is a mockup that some designer did that fused (the bad parts of) Messages with the background color on this blog and then posted it on HN.
Maybe the designers should learn how to skin Adium and do this? I fail to see why they can't?
There is a limit to what you can skin in Adium and some of those things you just can't change so even if you make the messages view look beautiful the tabs for each conversation are un-theme-able.
