If you heat one of the baths.. Presuming the stop and then chill the fix
you can get that accidental cracking that you got. It comes from
expanding the emulsion and then quickly coooing it to contract it. You
get sortof like a spiderweb look to your images. :)

How about letting your temperatures diverge by say 10 degrees or so
between developer/stop/fix?

That should give some grain coagulation - or articulation - whatever
it's called. I did SOMETHING by accident once that gave substantial
grain in Delta 400. I think it was a big temperature differential
between developer and fix.
