interaction and control

Although the form and design of my project is still undecided, I have started looking into the interaction aspect of my project and control of the lighting intensity and specific colour.
I have been researching the Arduino micro controllers.  My knowledge of controllers is very limited but they seem cheap and relativley easy to use for a novice.

I found a possible Arduino shield that is specifically designed for sequencing and controlling el wire

EL Escudo
COM-09259    

 From looking at the controllers If I used a sheild for the EL wire it would be ideal for the sequencing I want to use.

Already price is looking to be a huge factor so hopefully I can get these items relatively cheap.

Im unsure of if I shall use human interaction to physically move it or if It will rely on motors. If I use a motor Im not sure If I will control it through the arduino. at least not at this stage.
