A pet toy and exerciser which produces an automatically movable, outwardly projected laser beam. The function thereof is to provide virtual "prey" for the stimulation and exercise of an animal. The device, which does not include a conventional motor, is small (e.g., can be handheld), lightweight, battery operated and silent, and has an extremely long potential cycle life. Electrically energized nitinol wires deflect a visible laser module to produce a virtual laser light target moved through three dimensions.

An automated can decorating apparatus according to claim 1, further comprising a trip arm extending generally in a direction radially away from said stub portion, the trip cam follower mounted on said trip arm; a reset arm extending generally in a direction radially away from said stub portion and angularly spaced from said trip arm, the reset cam follower mounted on said reset arm. 3. An automated can decorating apparatus according to claim 2, further comprising a common sleeve fitted on the said stub portion and said trip arm and said reset arm are connected to said stub portion by said common sleeve. 4. An automated can decorating apparatus according to claim 3, wherein said trip arm and said reset arm are integrally connected by said sleeve to form a unitary body. 5. An automated can decorating apparatus according to claim 1, further comprising an off-center spring connected to a first spring post disposed on said trip cam follower and a second spring post disposed on said support member, wherein said off-center spring pulls said mandrel toward a printing position when said reset cam follower is moved in said second direction and said off-center spring passes over said stub portion. 6. An automated can decorating apparatus according to claim 5, further comprising an adjustment mechanism for adjusting the contact pressure between an outer surface of a blank can that is received on a said mandrel and said printing portion of said blanket wheel, said adjustment mechanism including an adjustable member that abuts against a wall portion connected to said stub portion, wherein said adjustable member imparts force upon said wall portion for twisting said stub portion for selectively relieving or increasing tension in said off-center spring, thereby adjusting the pressure between an outer surface of a blank can that is received on said mandrel and said printing portion of said blanket wheel. 7. An automated can decorating apparatus according to claim 6, wherein said adjustable memb
