     There are many famous museums throughout the world where people can enjoy art. Washington, D.C. has

the National Gallery of Art (美术馆); Paris has the Luvre; London, the British Museum. Florida International

University (FIU) in Miami also shows art for people to see. And it does so without a building, or even a wall for

its drawings and paintings. FIU has opened what it says is the first computer art museum in the United States.

You don'[t have to visit the University to see the art. You just need a computer linked to a telephone. You can

call the telephone number of a university computer and connect your own computer to it. All of the art is stored

in the school computer. It is computer art, produced electronically by artists on their own computers. In only a

few minutes, your computer can receive and copy all the pictures and drawings.

     Robert Shostak is director of the new computer museum. He says he starts the museum because computer

artists had no place to show their works.

     A computer artist can only record his pictures electronically and send the records, or floppy discs, to others

to see on their computers. He can also put his pictures on paper. But to print good pictures on paper, the

computer artist needs an expensive laser printer.

     Robert Shostak says the electronic museum is mostly for art or computer students at schools and universities. Many of the pictures in the museum are made by students. Mr Shostak said the FIU museum will make

computer art more fun for computer artists because more people can see it. He says artists enjoy their work

much more if they have an audience. And the great number of home computers in America could mean a huge

audience for the electronic museum.
