Desktop Theatre

Description
Desktop Theatre is a software that allows people to create interactive art.  In each palace (chatroom), this 2d room is filled with avatars that represent participants.  The Palace can let users to use Macintalk digital voice synthesis to "speak", so users can use their robotic voice to have a conversation with other users.  And our creative internet users have used this chance to create their internet drama.

Opinion
I think this artwork is a great example of net art.
Net art is the art only can be done in the internet, for Desktop Theatre, the drama is done by the users from around the world, this can only be done by internet.  And internet has helped this software to have some interesting characteristics.

Random, by Chance
Because of internet, users can get into different Palaces, to participant or even interrupt the other users' drama.  One new user can change the whole story of the drama, makes every dramas become different.

Different users can join the Palace and play their roles

LARGE topic variety
Also because of the internet, users around the world, share different religion views and culture can also participate in the drama.  So the theme and the topic of the drama can be in a great range.  Also, it is very interesting to see a drama which has different cultures inside, or we may even see the conflict between each culture in the drama, such as a drama which is talk about God and religion, and it is done by many users in different religions.  It is cannot be done in the real world.
