Art Show Ideas

Kinect Visualizer
Use data from a kinect and create a visual colorful representation of the human movements.

Musical Riff Generator
Create a program that generates a complete riff based on a single note that is played.

Virtual DJ
Use an MPC or midi controller to create a full beat/song. I would map loops to each pad so that anyone could be able to become a DJ with this installation.

Music Creational Tool
I would program an interface to generate some cool sounds. This installation would be all about manipulating beats/sounds. It would also save your work so you could edit what you made later.

Sound Visualizer
Put a microphone that sends it's audio data into a program which then gets represented visually on a display or monitor. Depending on how loud/intense the sound is, the visualizer will fluctuate in it's craziness and colorfulness.

Interactive Data Visualization
Use a relevant database of information that viewers can easily compare/contrast information to come to a conclusion. All the data would be organized and displayed and designed in a very easy way to operate. 

Art Robot
Create a robot with the function of generating a random art piece. The art piece would probably be a painting and the robot would be a moving arm with a paint brush. It would have a small variety of colors and would not create very complex paintings but more abstract. 

Musical Chess
This installation would be a game of chess that plays music with every move. Based on the position of the pieces, the music would be either soft or intense. Every time a piece is moved to another square, the music would change in some way.

Musical Light Show
This installation would have a series of colored lights that would move to audio. The color and experience would almost give a concert or live feel to the music.

3D Visual Experience 
Create a visual representation of specific topic in 3D. This display would show users meaningful data (possibly a timeline of events) of something which flys towards you, similar to the into to star wars (but flying towards you). It would be an cool an interesting way to express information to a person.
