Art is essentially communication of an idea, thought or feeling. If its just cages hung on a bit of wood......its cages hung on a bit of wood!
If the guy who did it tells you......
" Its an expression of my latent desire to remove the last vestiges of individuality in a constantly changing social platform, where we are all individuals, but impotent to change our own path"
And you think...
"I feel his is inability to diversify his purpose whilst, simultaneously trying to maintain his animimity ....wow! How does he make that feeling so clear to me just using the medium of bottle cages"
Then its art.
