I think PuppyChow's was very, very similar. I've never seen one done w/cremations, though, so I've been working on this:
6rl 6rl 6rl 6rl 6rl 6rl 7dp 7dp 7dp 7dp 7dp 7dp 7dq 7dq 7dq 7dq 7dq 7dq 7n2 7n2 7n2 7n2 7n2 7n2 809 809 809 809 809 809
Haven't had an opportunity to test it at all but conceptually it makes a lot of sense to me. Feedback and ideas appreciated.
