This post is just great, and a nice definition.
According to Wikipedia, Steampunk is actually the term used to refer to fantasy and science fiction written in the Victorian age. A time when many machines were still steam powered. Now, if you were to describe a gadget as being “steampunk”, you’d be referring to a design integration of futuristic form with design elements and craftsmanship consistent with the Victorian era.
