What's old, what's new

A newly made replica of an old design: is that an old thing or a new thing? What if you take pieces of old, broken pottery and assemble them into a mosaic, a new work of art? What about an ancient piece of machinery that's had every part replaced with a new part over the years?

What do you have that's a perfect blend of old and new?

This week's theme is old things and new things.
