Some of my friends blame me for my free using of arts, music, movies etc. Free - does not mean 'free of charge', it means free of worship the artists, musicians, etc. I use arts as ingredients for my life mix, like spices for cousine. I have found a good essay which is very closely to my mind about art: Art would be designed for adaptation and re-use. It would never be the finished item because someone might be adapting in some new way.
The National Gallery in London is free for visitors. We can 'withdraw' any images 'deposited' by artists.
