In design, inspiration is pulled from many places. A place you've been, a time in your life, a simple story. Lately, I've been feeling inspired by the contrasting geometry in Russian Constructivism. Below are a few images.
First is the cover of a book on construvist architecture from the British Library that focuses on the comparitive contrasts of the organic and mechanical using a human hand and compass. The overlay of the text is often important to emphasize the underlying geometry of the composition.
The next image is a propaganda poster by El Lissitzky entitled "Beat the Whites with the Red Wedge"
Also, see it's influence in an album cover from Franz Ferdinand.
