Well, like all design movements SteamPunk is distinctive and has a number of unique characteristics.

It can really be considered to be a useful antidote and alternative to intensive CADCAM and machine made products. Developing useful functional products that have both an historic and iconic flavour is easy. It's personality is an ever so slightly Gothic meets Art Deco rebellion! Essentially SteamPunk is product design with a twist. Curves, connections and detail can be prolific or sparing.

The most likely to use materials includes copper, pewter, wood as well as steel sheet, wire and tube and leather-look PVC cloths. These offer a substantial range of working processes that are otherwise side stepped in a present day homage to CNC cut parts and components.
With the potential for finishes and surface decoration that lends warmth and leans to detail, SteamPunk also has a monochrome aspect making sketching, shading initial ideas easy to develop.

Strong aspects of SP include that of keeping and of value and long term ownership rather than something transient.

It is also a point where Art and Design and Design & Technology can comfortably meet.
