Reusing glass bottles?

I have quite a few brightly colored glass bottles, some of which are damaged, so cannot be re-filled, and they have very pretty colors, so I don”t want to give them for recycle.
Can I cut shapes out of glass bottles (if yes, which glass cutter is the best for curved glass?) – if this is possible – what to use to get rid of sharp edges (apart from sand paper – it’s very time consuming..) or maybe I can break them and use for mosaics or any other decorative use?
I am concerned about the sharp edges of those bits though. maybe there is some machine which can tumble them like they do with natural stone tiles? (I am not sure how they do it though..)
