I found out alot more by going to the blog called the Steampunk Workshop. Basically, it is sort of an imagination based concept of what would things look like if some of the Victorian ideas like steam still worked to run modern technology. They look back at some of the ideas from classics like Jules Verne and science like the Babbage engine. It is also a bit of recycling and reworking thrown away things like typewriters.
Anyway, I think some of the items are cool! and I love the scifi "historical" adventure feel to the whole thing. We recently watched the film "City of Ember", which also falls into this genre.
I also took several of the types of gadgets like astrolabes which inspire the ideas for Steampunk. I will show some of those tomorrow. I discovered I missed a talk on Tuesday about Steampunk and fashion!
Additional info on the exhibition: I just found out that there is a video about the exhibition and an explanation by the curator about Steampunk and some of the gadgets.
