bilboard layouts

I wanted to make the bilboard more interesting, and interactive for poeople. i had ideas of having solar panels (since i have based my project on solar panels) and have then work through the day, collecting the sun, which then lights up the sign at night, maybe having buildings on the bilboard, which windows light up at night. also it is an non positional way to collecting energy, which also tied into my client, and his aim to recycle items, and to cause as les pollution as possible. 

this is the first page of ideas, i tried to think as many interesting eco ways i could think off. 

i started another page where i eventually thought of a good idea. 

i then developed that idea which was to have the sun collect heat from the real sun which then lights up the sign at night.

and this is my final idea layout.
