What's your best "upcycling" idea for vintage windows?

I found two windows on the curb down the road.

One is the kind that slides up and down with rope and a counterweight. The other I think originally opened outwards. Both are glass framed by wood with some of the original hardware attached. I don’t own any real estate so can’t use them as windows at the moment.

I’ve seen two ideas for reusing windows – using them as photo frames and using them as decorative pieces in gardens.

What would you do with these windows?
