Looking for a spectacle?

Not much from me lately - I've been having a busy week. I finally got a bit of lunchtime surfing in and somehow found my way to this:


It's a site devoted to the study of 16th to 18th century stagecraft, a subject that is cool enough to begin with, but these folks have computer animations of many of the different mechanisms in action - trapdoors, "flying" rigs, and sound effects (for thunder, roll a bunch of 30 pound iron balls down a special bouncy track installed in the top of the theater building.)

Pictured: halfway through the "Mnichovo Hradiste Scene Change"
