# Write a program that outputs all possibilities to put + or - or nothing
# between the numbers 1, 2, ..., 9 (in this order) such that the result is
# always 100. For example: 1 + 2 + 34 – 5 + 67 – 8 + 9 = 100.

# Hacky version:
["", "+", "-"].repeated_permutation(8).each do |operations|
  string = (2..9).zip(operations).reduce("1") do |str, (operand, operator)|
    "#{str}#{operator}#{operand}"

# A demonstration/exploration of generating animation "frames" by combining
# objects that emit sequences of frames, with the following goals:
#
# * Declarative syntax for convenience and readability
# * Composability, for easily assembling larger animations from smaller pieces
# * Interruptability (see Flagged), so an animation sequence can be interrupted
# * Lazily-evaluated combinations so clock-based animations can be mixed.

# A top-level animation.
