POP UP TREE

A tree made by folding a single sheet of paper. No glue, no scissors.

Its form comes from the "tetrahedral kite" that Alexander Graham Bell, inventor of the telephone, devised in the early 20th century in his quest to fly: small tetrahedra join into larger ones in a fractal pattern. Here, that fractal rises from a single sheet.

It folds flat to A4 size and opens up again whenever you like. Display it on a shelf, a windowsill or a desk, and color it to make it your own.
