Net art is characterized by its use of digital networks and the internet as its primary medium. This allows artists to create and distribute their work in a global and decentralized manner.

Net art often engages with issues of identity, politics, and social justice, as well as the impact of technology on society. Artists use net art as a platform to express their views and perspectives on these important issues.

Net art has been used in a variety of ways to promote activism and social change. Artists have used it to raise awareness about important issues, mobilize people to take action, and create a sense of community and solidarity among activists.

The project involved creating a fake website and video that made it appear that President George W. Bush had given a speech in which he apologized for his actions in office. The project was intended to raise awareness about the negative impact of Bush's policies.
