How does one describe installation art?

Techniques used in installation art:

Installation art is when an artist makes an artwork, but its not painted, or a sculpture, its like a video.

This website, is really good and it has heaps and heaps of videos by artists. Its like a profile. there r like 100 artists and some of the descriptions are resume, artwork, profile etc. Each link you click on comes up with its own page. (the artist has made its own page for its info. artwork) You can even search for your own artist.
