I had to draw a quick perspective of the project i'm working on for architectural design class. So i did. and then gave it this brush effect thing on photoshop CS4.
It's a gymasium with a geodesic dome (part of it) with its glass all being photovoltaic and absorbs the heat and reflects it in colors.
and it all works in a sustainable way etc etc etc (i'm not giving a lesson here XD)
