I found a few fascinating and well polished videos on YouTube concerning Steampunk as an art, an aesthetic and a social group. Take a few minutes with your favorite cuppa, and have a look!

• Off Book | Steampunk | PBS Arts
• Steampunk exhibition at the Museum of the History of Science, University of Oxford.
• Make: Steampunk Aesthetic and Design with Jake Von Slatt
• Steampunk Studio – Abney Park – Airship Pirate

Any other good substantial ones you know of?  Throw some links into comments and share!
