How do computers expand artistic creativity?

Computers allow people access to different types of media, which they can combine and incorporate into works of art. There are different ways for artists to portray their thoughts and ideas. Computers allow people to work with moving images and let people incorporate sound and other forms of media. Computers also let people alter images that have already been created, and allow them to incorporate these into their artwork. Because of computers artists have more tools to use, and it is easier to create and share one's artwork with others.
