Simple and Flexible CI
Easy to use corporate identity, with a simple key visual rule: The blue and green shapes have to cut at least two corners of the medium (what ever it is). Blue has to be higher than green (like the sky, which is always over the green earth).
The shapes represents a zoomed in and stylized wind turbine. The shapes can be also filled with images or cut every corner of the medium, which results in full colored page or screen ;)
