One of the artists that fascinates me is Andy Goldsworthy -- he creates really interesting works of art using only natural materials found at the site of production. Some of his art is intended to last for hundreds of years; some to last only a few hours...I'm getting ready to turn the big 50 next month, so I thought I should go outside and play in the dirt like a kid today... I tried my first attempt at "environmental art" and made two artificial flower pieces using only parts of plants and flowers found elsewhere in my yard.
It was a fun way to spend a few minutes. I have a new appreciation for the amount of time and patience Goldsworthy spends on his art!

I really didn't have an advance plan of attack for these, just cut some plants and played in the dirt. The flower to the left is made from parts of four plants, the one above from two.
There is a very cool documentary on Andy Goldsworthy worth renting that shows him creating his art. One of my favorite segments shows him creating a "thread" of icicles that appears to be threaded back and forth through a vertical slab of rock -- completed just before dawn to take a few pictures at sunrise, all gone a few hours later. He also does some impressive stone work, dynamic art in streams, etc.
Check out some of the pictures of his work on the web and if you like what you see, go rent the DVD "Rivers and Tides" to see him and his art in action (literally).
And in keeping with the "new things" theme, I tried making a short time lapse video of the above. Maybe I should stick to Hot Wheels and dump trucks! Don't ask what I was trying to do with the line of flowers, I don't have a clue...
