Came across this awesome construction project to create a steampunk computer keyboard. I am not sure what the 'touch' is like - but it is awesome anyhow - such style.

The stempunkworkshop article for the keyboard has a range of images and video covering the construction as well as design drawings. The site has details on a suite of other projects - lotsa fun like the Steampunk Motorbike!
Another site worth checking in this area is the MAKE blog.
