I'm only jealous I didn't have a mower like this growing up. In a spout of part ennui part creativity I cranked out a design once after pushing and pulling and picking up the trimmings wih a rake. My father was amusd until he got a call from the homeowner's association. To this day I still do their yard, lining up my reluctant newphews to take over. I bet this would get their undivided attention, balls and frisbee-like patty's of grass. Yep, they'd be excited to mow lawn, and I'd be excited to just sit back and watch them!
