I have encountered beautiful photographs of Zentrale, the Steampunk Synth. I am not sure of such a device actually exists, but I am trying to find out. In the meanwhile, check out this information about Steampunk and those beautiful photos!
Steampunk is a sub-genre of science fiction and speculative fiction, that came into prominence during the 1980s and early 1990s. The term denotes fictional works set in an era or world where steam power is still widely used — usually the 19th century, and often Victorian era Britain — but with prominent elements of either science fiction or fantasy, often featuring futuristic technology as the people of this historical period would have envisioned it to look like, i.e. based on a Victorian perspective on fashion, culture, architectural style, art, etc.
Steampunk is often associated with cyberpunk and shares a similar fan base, but developed as a separate movement (though both have considerable influence on each other). Apart from time period and level of technological development, the main difference between them is that steampunk settings usually tend to be less dystopian than cyberpunk.
