Description: One worm, one bad night in 1988, and the internet learned what 'wormable' means. On 2 November 1988 a self-replicating program got loose on the internet and copied itself from one Unix machine to the next, using weak passwords, trusted-host logins and bugs in common network services. Machines across universities and research labs slowed down or had to be pulled off the network while administrators worked out what was happening. It became known as the Great Worm. It was one of the first worms to spread across the internet, and it led to the creation of the first computer emergency response team. This pen-and-ink design shows a big segmented worm coiled around a boxy 1980s workstation. The workstation is wired into a period-accurate thick Eth

Description: Patch Tuesday was supposed to be once a month. The vulnerability count had other plans. PATCH TUESDAY over a giant red EVERYDAY, above a bar chart of published CVEs per year from 1999 to 2026 drawn as rising towers in a bold constructivist poster style.

Headed "On the Second Law" and captioned "Fig. 1. Left alone, order does not come back." Printed in cream and rust red for dark shirts. For physicists, chemists, engineers, science teachers, students and anyone who has watched order quietly slip away.
Description: Listen. Identify. Log. A retro field-guide chart for radio listeners, with six common signals laid out like bird-watching cards: FM radio, aircraft, weather satellite, pager, garage remote and weather station. Each card has an icon, its frequency band and a waveform sketch of its modulation, from smooth FM to on-off keyed remote bursts.

Description: A reverse shell is a great thing to use when getting out of a workstation back to your listening post, hopefully bypassing perimeter firewalls. Though here it could also reference a shell gained by reverse engineering some code or hardware. Either way, the shell helps us get one step closer to our objective.
