This one was done after the customer sent me a 14 page letter detailing what he wanted.  Twice.  By real mail.  And twice by email to be sure.  Followed up with tons more email and phone calls.  Making "custom" cases is work.  I'd rather be an artist who creates for me first and then sells rather than spending so much time selling and then creating.  But I digress, the case turned out nicely I think.  The idea here was to allow the tooling to wander around the case kind of like the clinging vine
