This TED video reminded me of one of the Academy’s posters. Some have suggested it’s one of the most confusing. There are blue AFs and purple Fs with positive and negative signs. Boxes drawn around the pairs suggest relationships between the Federalists, the Antifederalists, the constitution and the anti-constitution. Remember that one?
In this 3 minute video, Derek Sivers suggests, whatever great idea you have, you might also consider that the opposite is also true.

And let’s not forget… the right answer to the wrong question is the wrong answer to the right question.
Great stuff! For years, I had an “upside-down” image of the earth over my whiteboard (blackboard?); I need to bring that back.
Another neat contrast in thought shows through gardens: linear, British symmetry vs. winding, Japanese asymmetry. Each beautiful. =)
