Well, obviously pretty easy once you have "print_byte" and their ilk.
Without any such helper functions, something like

\new RhythmicStaff \with { \omit TimeSignature }
{ \time 1/8
  #@(map (lambda (s) #{ <>[ address@hidden s64] | address@hidden r64 | 
address@hidden c'64 \break #})
         (map (lambda (pattern)
                (map (lambda (bit)
                       (if (logbit? bit pattern)
                           #{ c'64 #}
                           #{ r64 #}))
                     (iota 7 7 -1)))
              (iota 16 224 2)))
}

would seem like a reasonable starting point.
