The green wine bottle challenge

Somehow over the past several decades the Phactors have accumulated 300 or so green wine bottles of the standard type with shoulders. All of them have been cleaned of labels and there are a variety of green hues from dark green to pale green. Now having expended this much energy just recycling these bottles into more glass seems a waste. What the Phactors want is a thing of beauty and a joy forever, something fanciful and perhaps aesthetically pleasing, perhaps whimsical, perhaps something funky to grace some spot in their gardens. But what? So this is the reader challenge. What can be done with these wine bottles to enhance our gardens? Your ideas are welcomed. Point us to somebody else's great idea. This doesn't have to be a do-it-yourself type of project. Just as we were to pose this question to a local glass artist, a young ambitious fellow, the old warehouse that housed his studio and ovens collapsed and rather abruptly brought an end to his glass workshop, a bloody shame. So let your imaginations run wild.
