ILLUS TRATION B Y JON HAN
about the cover: An open source Processing application
developed by computer scientist turned artist Leander
Herzog generated the graphic for this month’s cover and
story opener on pages 72–73. Herzog notes working with
code offers him a way to explore visual ideas very quickly,
as the code breaks the relation between complexity,
precision, and time, which often limit the design process.

Virtual Extension
As with all magazines, page limitations often
prevent the publication of articles that might
otherwise be included in the print edition.
For this reason and to ensure the timely
publication of high-quality articles, ACM created
Communications’ Virtual Extension (VE).
VE articles undergo the same rigorous
review process as those in the print edition and
are accepted for publication on their merit. In
addition, VE articles are listed in the Table of
Contents of the print magazine and are paginated
and fully citable as is every article published
in Communications. VE articles are published
exclusively in the ACM Digital Library.
The following articles are an extension of the
September 2008 print edition, now available to
ACM members in the Digital Library.
