[Cryptography] The ultimate random source

I have a solution to the random number generator problem that can be built
for about $50 and is completely verifiable.


1 Web Cam capable of focusing at a distance of 6" or less (can use a
correcting lens if necessary) neither resolution nor quality is critical.

1 Conical flask as used in chemistry, about 6" high.

1 packet multicolored candies (smarties, skittles)


1) Dump the candies in the flask, shake, take a photograph with the camera,
take the SHA256 hash of the photograph to acquire the 256 bit seed.

2) Shake flask vigorously, repeat step 1 as needed

3) Eat the candies

I'll do an instructable video maybe.
