What a splendid idea!
Triboro Design Solutions (a husband and wife team consisting of David Heasty (the husband) and Stefanie Weigler (the wife)) don’t just publish the final results of their work for different clients on their portfolio site, they also have a special section called Triboro Leftovers where they showcase, well, the “leftovers”: type treatments, photos, sketches, illustrations, etc… They stripped the pieces of their original context and meaning so they become “remixes” which are able to stand on their own.
They would like to create different volumes of leftovers, each with a cohesive mood or feel. At this point, they only have one volume, but this sure has a lot of nice stuff in it. Take a look at some examples here, or check out the complete Volume 1 of Triboro Leftovers on their site.
