Unsightly stump in front yard. Took bowling balls and drilled holes through one of the finger holes, did not go all the way through. Drilled holes in stump at angles. Inserted rebar in ball and stump. Told my landlord that the stump was sprouting.
Use car wax to shine the balls. After a few years (8) they are cracking. Adds character.
Here I have taken some of the balls off their rebar stands so you could see the process. The rebar is from Home Depot already cut into 12" length. I put a big drill bit (same one used to drill the hole in the ball) the size of the rebar and drilled the holes in trunk at a pleasing angle. Then slid the ball on the rebar. Nothing is permanent...I like to be able to change my mind.
Here is how they looked this morning after a light dusting of snow.
