While some people are going really eco by using real sheep to trim their grass, some still prefer machinery. This robotic lawn mowing sheep achieves the impossible by making lawn mowing fun to do and watch. It was grazing in Chicargo's Millennium park for NextFest 2008, flanked by signs proclaiming "Sheep at Work, Please Do Not Disturb."
The best mower was Osman Khan as a reference to the Philip K. Dick book Do Androids Dream of Electric Sheep. Random fact: this was also the inspiration for Bladerunner.
This sheep can mow large lawns with the help of a remote control. Just when you think it can't better, it transpires that is can also talk, bleet and sing "Mary Had a Little Lamb." ROCK ON!
