When of the pretty 3D wooden puzzles I bought on the streets of Yogyakarta had disassembled itself I was very very worried that I would have a much less decorative mound of wooden pieces on my desk for ever and ever.
Luckily I have colleagues.
They are, like most scientists, the kind of people that can niggle at a problem for ages, regardless of it’s relevance. And they can be be disproportionately happy about solving it. Study their cooperation on this particular puzzle and their infectious glee at finally getting it. Enjoy!
