The Free Universal Construction Kit Mar 19 2012
The challenge facing children of the last half generation of how to connect their LEGO pieces to their Lincoln Logs to their K'Nex has been solved by The Free Universal Construction Kit and access to a 3D printer. (Did they choose the name for the acronym?) Apparently Construx have fallen so out of favor the Kit does not wish to connect them with pieces of other species. They should have made the list on the strength of this theme song alone.
Old man says: We never had this problem when playing with wooden blocks.
