Ahh - I came across this problem several times in the past, and I ended up
learning about low-discrepancy sequences - which are completely non-random, but
more "randomly" distributed than a real random sequence.

My code for a halton sequence is:

#macro halton( index, base )
 #local out = 0.0;
 #local fraction = 1.0 / base;
 #local i = index;
 #while( i > 0 )
  #local remainder = mod( i, base );
  #local out = out + (fraction * remainder);
  #local i = int(i / base);
  #local fraction = fraction / base;
 #end

 out
#end

The base value is a prime number (the smaller the better), and the index can be
your brick number.

Get a value out of it with "halton( brick_number, 2 )".
