For Father's Day this year, I embroidered Fermat's Last Theorem on a polo shirt for my dad the enginerd. You can see the embroidered letters peeking out of the collaged box I made for wrapping the shirt (the letters appear logo-style on the left of the shirt when worn). For the sticklers - yes, I did leave off the "for all n>2" for space considerations... I was just so happy to come up with an idea for something handmade for him. Anyway, Dad loves it.
