If you haven't already heard of him...

Joshua Allen Harris is the name of the artist who used the exhaust pouring from the subway vents around New York City to erect his temporary plastic sculptures. Polar Bears, Giraffes, and even a Loch Ness Monster...Harris started with just one tiny bear- as an experiment, and gained rapid popularity among pedestrians- who photographed, you tubed and tweeted the images of his work.

On another note, plastic bags! What a ubiquitous sign of our times. An ever present eye sore strewn along the streets of big cities and populated areas, a symbol of man kind's stamp on the enviornment, and now a viable artist's medium. People are doing amazing things with plastic bags these days, resurrecting and recycling the old staple and bringing awareness to the world that, well, we don't really need any  more of them! 

Bags, rugs....mostly bags, and art can all be made from recycled plastic materials. Anything that can be crocheted can be done so with stripped plastic bag 'yarn'. The above purse is from ecoist...which is definitely worth a browse.
