- Gifts for Math LoversPenrose tilings, Voronoi diagrams, Nash equilibria — mathematics drawn correctly, from a $3 decal to a heavyweight hoodie.
- Gifts for National Park LoversYosemite, Zion, Grand Canyon, Rainier — topographic tees drawn from real elevation data, plus tide-table coastline tees.
- The Gift EditThe full gift shelf, across every series.
