Hi everybody !
Today I revisited CPAN and tried a cool cpan module :
http://search.cpan.org/~woldrich/App-xkcd-0.082/xkcd
Yes there is a nice xkcd_viewer.pl for X (as package in OpenBSD) .. but this one is both for cli (retrieves text) and for X (with feh) .. if you issue 'xkcd -l' while on X you'll be greeted with the latest.
(Although some might see that part of xkcd charm is quite pictorial)
