activity triforce

for those of you who may be familiar with activity theory, the following might look familiar.

this is the usual depiction of Engeström's version of the activity theory model: one large triangle decomposed and subdivided into what appear to be other, smaller triangles. however, I just saw another, somewhat different depiction.


hm, interesting. for the moment, nevermind the slight differences in the naming of the nodes. instead, I would like to draw your attention to the similarity between this and another symbol, one I recall quite fondly from my childhood.


that's right, the Triforce from Nintendo's Legend of Zelda series. Engeström's analytic approach to human activity is really the modern day incarnate of the ultimate golden power from ancient Hyrule.

...ok, I'm done geeking out now, time to get back to work...
