Self-styled "Datamancer" - Richard "Doc" Nagy is well-known for his unique and inspirational "steampunk" contraptions, which can be seen on TV shows such as SciFi Channel's Warehouse 13, who contracted with him to have some special props made. Nagy uses a lot of creativity and ingenuity to combine modern technology with turn-of-the-century and medieval-inspired decorative designs--resulting in truly unique and useful art.
One of my personal favorites is the "Archbishop" Gothic PC, [above] a PC/LCD/Keyboard/"Mouse" combo that was built using Gothic design elements. The LCD monitor lives inside a scratch-built Gothic arch with quatrefoil designs and stained-glass doors. The PC case features the same Morisco-patterned glass, brass embellishments, a hinged lid for access to the drives and hardware, and soft, ambient red lighting. Built as a gaming computer - it's a real high-performance PC, not just a showpiece.
While this particular model is sold, Richard will be happy to build another one for you upon request. While "steampunk" inspired design might seem to be at the very edge of what we cover at TLG, the Victorian and Gothic themes used in so many of the designs are quite appropriate to Medieval and Tudor interiors. After all, there can be little doubt that the "Archbishop" PC would look better in your library than a beige box.
