For entropy generation, dice have the limitation that physics is 
going to typically force them into alignment, at least with the flat 
surface on the bottom and possibly horizontally with each other, as 
opposed to the much more random positioning of the candies which a 
camera can take advantage of.

Also, Phill's method means you get to eat the candy when you're done, 
at least if they're chocolate, though it's somewhat counterbalanced 
by the failure mode that somebody eats the candy before you've got 
all the random numbers you need.
