Though computers weren't around during the Industrial Revolution, if they were, their keyboards would look something like the 'Sojourner' keyboard from Datamancer.net. Plated in brass, backed with aged leather and with cursive parchment keys, the Sojourner is fully functional with any modern computer that accepts a wired USB keyboard. The Sojourner keyboard was designed by Richard "Datamancer" Nagy, a steampunk artist, designer and maker.
The Sojouner keyboard is more than just a functional consumer keyboard. It was used as a prop in the SyFy network's 'Warehouse 13' series. And if a steampunk keyboard is in a SyFy show, it definitely looks good.
