thanks.. interesting method. But the ultimate question is, if the order of @words is randomized, how would i re-order @order so that it still produces "this is a sentence" ? pseudo code: 
@words = "this is my sentence"
@order = 0, 3, 1, 2
print @order

randomize(@words)
@order = 2,1,0,3

randomize(@words)
@order = 1,0,3,2

the code is somehow keeping track of changes in the @words array and updating the @order array.
