The theme of this 2014 DCA conference is:
Design & Graphic Palimpsest: [Dialogue-Discourse-Discussion]

The word "palimpsest" comes through Latin palimpsestus from Ancient Greek pa??µ??st?? ( palímpsestos , “scratched or scraped again”) originally compounded from p???? ( palin , “again”) and ??? ( psao , “I scrape”) literally meaning “scraped clean and used again”. Romans wrote on wax-coated tablets that could be smoothed and reused, and a passing use of the term "palimpsest" by Cicero seems to refer to this practice.

From Wikipedia:
A palimpsest / ' p æ l ? m p s ? s t / is a manuscript page from a scroll or book from which the text has been scraped or washed off and which can be used again. The term has come to be used in similar context in a variety of disciplines, notably architectural archaeology and geomorphology
