Talking about steampunk laptops and keyboards barely a day ago, I've come to know that John Coulthart, an artist and designer based in UK whose works are truly fantastic, has also recently created the following steampunk design for Modofly. Nice work indeed.
Besides, you may want to take a look at Dana Mattock’s incredible Steampunk Frankenstein casemod at Flickr. I wish I can have one myself -- Oh yes! How I wish. I'm very well aware that this does not come cheap. A steampunk keyboard from Datamancer will cost you USD1,200.00 onwards depending on the design and materials used.
