"Convex Concave" is an M.C. Escher inspired 2-dimensional assembly puzzle from the incredibly creative and artistic mind of computer scientist, prolific puzzle designer, and master of the ambigram, Scott Kim. It was used by Scott as his exchange puzzle for the IPP23 Puzzle Exchange at the Chicago Puzzle Party in 2003. The object of the puzzle is to use the 7 magnetic pieces to form a variety of 3-D appearing shapes in 2-D!
The puzzle is as it was received at IPP23 in 2003 in Chicago, unopened in it's original packaging with all of its original paperwork. I will provide a
copy of the solution to "Convex Concave" from the IPP23 booklet.
I will ship "Convex Concave" within the US as a ground advantage
(first class) package for between $7.50 and $8.50 depending on postal
code, or at insured priority mail pricing for between $10.50 and $15.50 depending on postal code, if preferred. I am happy to ship
internationally at cost, likely around $30 for an object of this weight, but I
cannot always guarantee that overseas
packages can be insured or tracked. Please do not send payment until the
postage cost
is determined. Note, sadly, that tariff wars may be in effect for
packages received in certain countries.
Please let me know if you have any questions regarding my copy of "Convex Concave."
Thank you for viewing my auction!
