Lazy Saturnday

So I was thinking it’d be kind of neat to set up some sort of mechanical (possibly using Legos) device to move a laser pointer around to entertain animals. Then I was thinking… you could have it set to repeat the same pattern, and videotape your animal(s) reactions. You could even have it come on for sporadic periods through out the day and see if the animals can remember when the “red dot attacks” each day.
