Beach Art Roomba

Solar powered, uses triangulation location of either GPS or local WIFI systems to know where it is. Moves very slowly and obviously avoids people on the beach with visual and other sensors, even incorporating the path around the beachgoers into the art piece.

Saw a gal making beautiful art on the beach the other day by shuffling her feet, thought it would be cool to know your beach would always have a different work of art being created at all times, at least on one portion of it.

Could also make it pick up garbage and deposit in in a sealed portion of a continual garbage bag. Kids would probably follow it around hoping the be the ones to take the bags to the garbage cans.

So the garbage pickup thing could be a bonus, but mainly you'd have beautiful art that was constantly changing.
