a game for spatial reasoning
BlockBuilder challenges and develops your ability to think about spatial relationships. In this simple game you build and manipulate a block structure both mentally and on the screen. What three letters does the block structure above show?
What's special about BlockBuilder?
This game was invented by Scott Kim and me in 1992, with the help of Rolf Faste. The development was done as a project at Stanford University supported by the National Science Foundation Synthesis Engineering Education Coalition.
What three letters are at the top?
it occurred to me that a letter could be reversed -- made white on black.
I excitedly dismantled my previous attempt and built a reversed 'S'.
From that moment I became a BlockBuilder believer. Not simply because
it's a delightful puzzle, but because it fosters the kind of fluent
and flexible thinking that's at the heart of a vital design experience:
personal engagement with the problem, a vibrant action-reflection cycle,
iterative problem solving, visual/analytical ambidexterity, etc. For
more on this go to the classroom. Yes, the three letters are "NSF".
