The following video shows some interesting puppet mechanisms, both mechanical and pneumatic. The people in the shop are constructing bird puppets for a 1999 Coca-Cola television commercial. Perhaps more interesting is that Jamie Hyneman is working in the shop as well, years before Mythbusters appeared on TV.
I just finished building a six foot tall microscope which resulted in some nice photographs. I guess at six feet tall, it’s not really “micro” any more; it should just be called a “scope”.
A company with a microscope as its logo wanted a giant microscope to bring to trade shows. They wanted the silhouette of the prop to match their logo (which was simply a drawing of the side view) but with some details added to make it look more like a real microscope. One of the challenges was in designing a prop that looked like a real microscope but still resembled the outline of their logo when looked at from the side.
