This is a play on the word "redundancy". I thought of making a pun from the word "redundant" and the letter "C" and how it would sound the same as "redundancy". The way to present it was to show it in an alphabet with two "C"s. The first design I submitted to Threadless had only an alphabet in Helvetica with two "C"s, but was declined. In this version I have made it more illustrative with children's blocks and two "C"s.

pretty cool. i like the ABCC blocks. They work together well as a graphic. What if the explaination was at a diagonal above the two cc's and more subtle?
