Wow.

Normally, Vector expects its pitch to be a floating point number, or some kind of number. Well, how powerful would it be if I could say this:

object.vector.pitch = RandomValue.new(360)

…and have RandomValue present itself as a different random number each time it’s accessed?

Turns out I can:

class RandomValue < Numeric
	attr_accessor :max
	def initialize(max)
		@max = max
	end
	def coerce(other)
		if Integer === other
			[other, to_int]
		else
			[Float(other), to_f]
		end
	end
	def to_int; rand(max); end
	def to_f; rand * max; end
	def +(other); x, y = coerce(other); x + y; end
end

r = RandomValue.new(10)
puts r + 5
puts r + 5.0
puts r + "5"

…let’s see, here’s what I’m thinking of so far:

RandomValue
InitiallyRandomValue
ModulatingValue
InverseValue
RoundedValue (say, to nearest integer, or nearest multiple of 90)

Wow.
