EXP Podcast #376: The Witness Debrief

After dozens of hours, a whole bunch of graph paper, and more
than a little frustrated cursing, we've come to the end of The
Witness.  Then again, maybe you never really finish The
Witness.  I know I'm still seeing line puzzles hidden within
every day objects.  In any case, it's time to debrief and
discuss what we learned about technological hubris, metaphysics,
and maddening line puzzles.
