I love glass sculptures but have no means for making them myself.  I was able to make an interesting sea jelly sculpture out of plastic water bottles using only a pair of scissors and a small candle.  It was quite fun heating and warping the plastic strips and then assembling the sculpture.  It was also fun to experiment with the different shapes I could make.

I think these would be really neat if there were dozens of them hung up and maybe lit up somehow.  It would be a neat garden installation.
