Random Sequence Generation by Cellular Automata

[AngleWyrm]

After reading Stephen Wolfram's article
http://www.stephenwolfram.com/publications/articles/ca/86-random/ , I've
been trying to develop an implementation in C++.

uint32_t ca_random()
{
static uint32_t left, right, center=0x49ef96bf, result;

result=0;
for(int i=0; i<32; i++){
left = (center << 1) | (center & 0x80000000) >> 31;
right = (center >> 1) | (center & 0x00000001) << 31;
center = left ^ (center | right);
result = result | (((center & 0x10000) >> 16) << i);
}
return result;
};

Any recommendations for improvement?
