The choice of the a,b,c,d,e,f parameters seems crucial, too: Even with 
<0,0,0> as the starting point, the chosen values make the sequence 
"explode" within a few iterations, while a=-.3 instead of +.3 already 
makes a significant difference (though the result is still dull, but 
that's a different story).
