== Final ==
For my final project I am proposing a proximity controlled light display. This will involve an infrared proximity sensor connected through the arduino to a high powered RGB LED light. The distance to the sensor will control the color of the light being displayed. Since I am using a high power LED, I plan on projecting the light against a wall so the entire wall is illuminated. I will most likely set up the sensor so that when you walk closer or farther away, the color of the light will change.
The thought behind this piece is the idea of proximity and personal space. Depending on the color at certain proximities, the color will either be inviting or not, prompting the viewer to proceed closer or further away. I need to put some more thought into how I will display the piece once it is built and try to figure out a way I can use this technology to create more of a discussion.
