One exception to dull imagery was the sight of an imposed spiral pattern
which kept re-arranging the digits of a photograph of something (it looked
to me like an aircraft carrier, wildly distorted). A nice whirling dynamic
image, though a bit repetitive, reminding me that once something is
digitised its 'original form' loses much of its authority, or stasis.
From
which we quickly learn the new convention that 'all conventions can be
changed'.
