Time Paradox Pins and Buttons
Description: "Plutarch told the story, Hobbes added a twist, and the question still divides philosophers: if every part is replaced, what remains? Gold and cream planks make the transformation visible at a glance. The Ship of Theseus: an ancient trireme whose planks are replaced one by one, shown mid-repair and as a sequence from original to fully renewed. Is it still the same ship? The classic puzzle of identity. For philosophy students and teachers, sailors and boat lovers, history buffs, software engineers refactoring legacy code and anyone who has changed a lot. A conversation-starting gift.

Description: A temporal-travel safety board handles the worst kind of additional passenger: another version of you. The center features the gull-wing DeLorean, the glowing-in-concept but flat-ink flux capacitor and the tri-color time-circuit display. The bottom diagrams teach checking the date, spotting a duplicate figure, and using the exit only when the other version is out of sight. The prohibited icon shows two versions of the same traveler facing each other, directly recalling the 1955 double-self risk in Part II.

Description: " '—All You Zombies—' " is a science fiction short story by American writer Robert A. Heinlein. It was written in one day, July 11, 1958, and first published in the March 1959 issue of The Magazine of Fantasy & Science Fiction after being rejected by Playboy. The story involves a number of paradoxes caused by time travel. In 1980, it was nominated for the Balrog Award for short fiction. "'—All You Zombies—'" further develops themes explored by the author in a previous work: "By His Bootstraps", published some 18 years earlier. Some of the same elements also appear later in The Cat Who Walks Through Walls (1985), including the Circle of Ouroboros and the Temporal Corps.
