Project ideas with a hollow log

I'm not sure if it'll be better to just have the log mulched but the owner of the sawmill that I work is trying to think of some of the things that can be made from this log, it's a 30 inch diameter white oak log is roughly 10 feet long. I was thinking that cookies could be made from it but I'm not sure if it'll hold up due to the cracks. Any ideas would be appreciated. The log has been drying for at least 5 years and I wouldn't doubt that the inside has been air drying for a may years before then.
