Log walkway/garden path

An old tree stump can be sliced and used as pavers or stepping stones to create great looking paths but if you're thinking about doing something like this make sure the wood is treated against rotting and termites, and that each piece is at least a 4-5 inches thick. You wouldn't want your hard work to rot away in a year or two. Also if the walkway is likely to be wet, consider covering the pieces with chicken-wire to avoid creating a super slippery walkway.
