what to do with this

Sweet chestnut.. Burr

Some time ago i remember seeing this piece as it came off the mll.. looked stunning when still fresh cut...

however it was put to one side and temporarily lost in the mass of other wood stacked out to dry..

It reappeared in a pile of "interesting" wood just the other day so it got planed and then the bark wane cleaned up.. its stunning but what to do with it?
