So, when I want the void to point back at me, do I have to loop over void* or over NULL?
And how many iterations?

For the void to point back at you just dereference the NULL pointer

as many iterations as it takes

void* x = &x;
char* ptr = (char*)&x;

while (1) {
    printf("%d\n", (unsigned int)*ptr);
    ptr--;
}
