# Flags passed to globe program each time.
# --led-pwm-bits=9 because long chain is otherwise flickery (default is 11)
# -a 3 for 3x3 antialiasing (use 2 or 1 for slower Pi)
# -t 6 is run time in seconds before exiting
# -f 1 fades in/out for 1 second at either end
# Can add "-p" to this list if you want poles at cube vertices,
# or --led-rgb-sequence="BRG" with certain RGB matrices, etc.
