Rabbitduck Plush
A soft plush based on the famous rabbit–duck ambiguous illusion. Depending on how you look at it, it can be either animal. The first release in our Ambicuties line.
Inq’s Curious Egg Molds
A set of three egg molds that transform ordinary eggs into unexpected shapes: a diamond, a six-sided die, and Einstein’s head. Designed to make a familiar food slightly strange and far more interesting.
Yellowcake Spring BreakT-Shirt
A spring break-themed t-shirt that has a simplified “recipe” for refining uranium-bearing rocks into uranium “yellowcake” powder, which is used as the basis for fueling nuclear power plants and making weapons. Educational, provocative, and intentionally ironic.
Periodic Snail Pin
A magnetic-hold enamel pin that shows an alternative organization of the periodic table of the elements, one of the most information-dense visual representations in science.
Ambicuties Stickers
A set of nine stickers based on the Ambicuties line of ambiguous figures. Each character appears twice, allowing both interpretations to be displayed.
