What gives card decks this unique power to create new meaning in the world? The basis of visual thinking is the analysis (i.e. disaggregation) of a complex idea into “nodes”, followed by the synthesis (i.e. reintegration) of those “nodes” through “links” into a new meaningful whole. At the most basic level, cards are “nodes” in search of “links”. Card decks as a problem-solving tool are powerful because we often know the parts of a problem or solution, but we don’t yet know how they fit together in an insightful way.
