Meet the Beachbot
I'm a gadget lover. High tech, low tech, it really doesn't matter to me, as long as it's a gadget meant to do interesting things.
Things like, oh, making cool designs on the beach. You probably didn't know that we were lacking that sort of technology, but (until recently) we most certainly were.
Back in the day, if you wanted a cool design on a beach, or other areas covered with sand, you darn well had to get out there and do it yourself. If you wanted a similar cool design in a cornfield, you had to wait for aliens to show up in a crop-circle mood.
Now, thanks to the Imagineers at Disney, you've got the fully autonomous Beachbot.
Think of it as a Roomba with an artistic streak.
