This is an updated post on my project so you can see how it is developing.
Spheres Of Influence is an Interactive Art Installation.
This means that it will feature an artwork where the viewer can play with the content. This is made possible  by interacting with the sounds and visuals. Motion tracking through live web-cams  or presser sensors will create the interaction.
The first thing that the viewer will encounter when they enter the installation or space is a 3 dimensional transparent sphere. A series of projected images and sounds are projected on to the sphere.
The  host is  a dark mysterious female figure who reveals images and sounds to the viewer.
To begin with she beckons you closer and reveals something hidden in her hand when this image has been revealed she calls you closer again  further narratives are played out through each interaction. 
These interactions will be triggered by motion tracking technology.
There are various Plug- ins that can be used to create the interactions . Processing and Gem are the  technologies that I am considering at the moment.
