This two-sided T-Shirt promotes learning; the front is labeled 'docendo discimus' sharply marked with the mouse under it trailing below the lettering. The wording (do-"ken-dO-'dis-ki-"mus) is Latin and translates to 'We Learn By Teaching." This is the motto of Irvine Underground, a hacking/security organization located in Irvine, California - USA.

Penguin Linux Tux proudly sits on the back of the shirt in a multiple color design holding a magnify glass as he examines the networks packets for passwords. The symbols around the shirt define some of the uses of the Tux in a computer security and hacking world.

Each shirt purchase sale goes towards the organization in their effort of higher learning allowing them to rent out space for meetings, purchase equipment needed and influence local law enforcement.

Makes a great gift for UNIX geeks, Linux Hackers, Advocates and friends, families, girlfriends so that they may be clothed. Purchase your Tux Penguin T-Shirt (aka shirt, t-shirt, t shirt, clothes) online and submit your photos once your wearing it!
