ephemeral , conceptual, ethereal art

The first category ephemeral art is art the is only designed to last a short time, the second category conceptual art is used to show an idea or a certain concept to a person who is looking at it, and the third concept ethereal art is art that is very sort and delicate but well refined. An example of ephermeral art can sometimes be masks most of the time they are only used for a short time and then are discarded. Masks are used in all different cultures for plays, or just to reflect culture or religion. I think conceptual art is very important because it really makes you think not just think its pretty and move on and to me that is when art is at its best. I did however look at some ethereal art and i found some beautiful examples at www.scribd.com
