after seeing this in chicago it got me thinking about
how it might have been done. i'm pretty sure there
has to be something to seperate each picture. the
window-as-gate wouldn't be enough. there has to be
some sort of shutter-like mechanisim to break up the
succession of pictures. i'm guessing there are little
dividers in between each picture (the size of which is
probably slightly smaller than the window) that
contains the light to each picture and creates
darkness in between each frame. this would create
the flicker needed to prevent the blurring together of
each picture, mimicing the function of the projector's
shutter.

this is just my assumption.
