This is a tiny detail from an unfeasibly large random walk made in Berkeley Logo. The code looks something like this:
; random dice walk, with colours for each of six directions
; scruss, 2021-07
make "ch {14 6 2 3 13 4}
make "dirs {0 60 120 180 240 300}
make "sides {1 2 3 4 5 6}
to walk
make "throw pick sides
setheading item :throw dirs
setpencolor item :throw ch
forward 20
end
