ah I see.. the splat either breaks an array into a list or pulls the 
list into an array, depending whether it's included in the def or the 
call

so

def my_method(*array_of_arrays) #takes a list
array_of_arrays.each {|a| print a}
end

my_method(1,2,3) #=> 123
a=[1,2,3]
my_method(*a) #=> 123
my_method(a) #=>[1,2,3]
