An idea I had, early one morning — a trompe-l’œil tato box, very impure.
A magician, perhaps, could work up some patter for collapsing the box, but it would be far beyond my talents.
Whist is an old game — I learnt when I was in school — all I remember is that the rules were strange, arbitrary and I was terrible at it. That, and you were dealt 13 cards at the beginning of the hand. Horatio Hornblower supported himself between the wars by playing whist — that was before I knew him.
Here’s a crease pattern — print it back-to-back and cut out along the edge of the cards. Ooh, concave edges and so impure! Relax, you can take a shower later.
Big shout out to David Bellot, who made the SVG cards used here.
I think this is more engaging as a curved box. Here the crease pattern for that.
