Probably back at the beginning of December, when that post was written.

The Stickman collection went for ~$35k awhile ago.

Puzzle Paradise currently has STC Unhappy Childhoods (#41) made by Neil (TheJuggler) available for auction.

I'm happy to have one on its way to me this week

I found a great resource online explaining why the Unhappy Childhood is such a great puzzle. To summarize, Anyone can find a solution as there are about 19k ways of assembling the 12 pieces into the box. Sounds easy, right? The pieces, however, are checkered, and of the 512 different ways of checkering these pieces, all but two pattern has multiple solutions. One of the remaining patterns is impossible to solve while the other has a unique solution. Guess which pattern the Unhappy Childhood employes

I'd also recommend buying the book: Geometric Puzzle Design
It's a pretty interesting read if you have any interest at all in geometric puzzles

I got a copy for Christmas, and after going through it I'm still constantly picking it up again and again. It's fascinating to see what goes into designing a geometric puzzle.

Mr Coffin pretty much blows my mind - how he comes up with those constructs and pictures them in his mind - is beyond me ... remember that most of that stuff was done well before the advent of PCs, and his work around rhombic dodecahedra is incredible (in the literal sense of the word as well!)...

(Also a big fan of the book - I even have two versions of it )

I ordered the book as well, but my wife is holding it hostage as a small birthday present

I think it's a brilliantly designed puzzle. Much more reliable than the last one. Quite easy to solve though.

Review going up today ... so yes
