# raise LEDS "up" the cube, like raising sea levels
# left and right rise together,
# Once left and right grid has reached the top,
# fill top panel in diamond pattern, starting from the user pointed away,
# towards the back of the cube.
#
# update: diamond pattern grid is complex, too much math for my liking
#
# Concept: "Rising Timer"
# Amount of time passed = rising led levels
# colors:
#   red - work
#   green - short break
#   yellow ? - long break
#   white - lunch break (?)
#
# Need to figure out a way to calculate led levels based on time passed
#
# Focus Time Timer:
# Need to get current time, add 20 minutes
# raise red level over 20 minute span of time
#
# Short Break Timer:
# After 20 minutes, make beep or sound of some kind
# start green raising levels, over 1 - 5 minutes
#
# Long Break Timer:
# after three cycles of red and green, do 10 - 20 minute rising timer
#
# Lunch Break Timer:
# Not sure if I need this
# After 3 - 4 Long Breaks (i.e. hours), take 1 hour lunch break
# What color? White? Magenta?
