What's the coolest application for an Autovent? Answered

Autovents are elegant, amazing wax filled pistons that expand when they get warm and contract when they get cold. They are used to automatically open greenhouse windows when they get too hot. I think they could be used in something like a solar tracker or a kinetic sculpture but I've never seen any innovative applications for them. Have you?

Only thing I can think of that you didnt mention - have one raise an 'acme style' (think wile-e-coyote) sign that says "damn its hot"...

I've never seen them used for anything else.  I don't think they would work very well for solar trackers because they seem to have a very limited range of motion.
