Today I received Bathsheba‘s Tetrabox: a 3d-printed steel sculpture which is also a puzzle held together with magnets.
At a minimum, it has what I think of as ‘tips forward‘ and ‘tips around‘ solutions. For the first, all three of the asymmetrical pieces have their extended tips pointing toward the one symmetrical piece, allowing the sculpture to rest on them. For the second, the tips circle around the symmetrical piece.
Previously, I got Bathsheba’s hemoglobin laser crystal for Amanda, and later Myshka got me the DNA polymerase crystal as a very generous birthday gift.
