I can point you in two directions on that, first of all there’s grunge style web design, and then there’s Russian Constructivism and othere same era Avant Garde art.
I’m probably being to vague, but it’s the general worn look of grunge and the more calculated style, or feel of Constructivism and related art styles.
Hope this makes any sense…
P.S. The look of the this is somewhat tweaked in development right now because of the work I’m doing for the events addition to the site. Small tweaks mostly…
