One of the things got this weekend from a buddy is what they call an interlocking metal disentanglement puzzle - two separate pieces of metal bar that are bent into sort of matching shapes, and linked together in such a way that you have to fiddle around to figure out how to sort of line up their sort of opposite gap parts so that you can then slide them apart, and then rejoin them by sliding them back together and then start over trying to get the sort of solution right again a bit more quickly thereafter - took me like 10 minutes first time, and now seems to be doable/solvable within like a minute or two each time now that have sort of built up a 3D visualisation of the target alignment/juxtaposition in my mind's eye - has anyone else tried out this type of thing..? Lastly, here's the wikipedia page mentioning this type of puzzle thing: http://en.wikipedia.org/wiki/Mechanical_puzzle#Disentanglement_Puzzles Stay well Jacob Kruger Blind Biker Skype: BlindZA '...fate had broken his body, but not his spirit...'
