I know Steampunk is my favorite way to waste time -- perhaps I'm not the only one? Leah at More Ways to Waste Time has a very thorough, pretty, feature on Steampunk in Home Decor and a previous post featuring Restoration Hardware's many Steampunk items. (I was going to do that post. Really!)
You know it's well researched when she finds "steampunk home" things that surprise even me -- like the work of artist David Trautrimas or decorator Will Wick (those I will do posts on -- they are too good not to!).
