An object with a tactile outer layer includes, for example, a ball having an outer surface and a series of protrusions or spikes on the outer surface. The protrusion each appear as a tear-dropped shape mass that includes a base having a relatively flat bottom adhered to the outer surface of the ball and a narrow tip and/or curved tail extending away from the outer surface. Manufacturing can be performed by mounting the object and utilizing injection arms that deposit elastomer globules on the object. The globules are deposited by pressure through a reservoir in the injection arm and the injection arms are then withdrawn to product the tail shape.

Disclosed herein is a sporting ball with a specific image printed on the sporting ball. The image is generated, selected, or captured by a user, which triggers a process for printing the image onto the ball. Further disclosed are systems and methods for printing and delivering the sporting ball with the image. The image may be an image of the user, a favorite sports athlete, or a celebrity. Certain preferred embodiments utilize a basketball, a soccer ball, or a football. However, alternative embodiments may include any type of sporting ball. The image may be captured by numerous means recognizable by those skilled in the art, including but not limited to a computing device, a cellular phone, a tablet, a web cam, a digital cam, and other traditional non-digital cameras.

An exercise ball structure coated with food-ingredient powders includes an inner elastic spherical-shell structure and an organic food-ingredient powder coating. The inner elastic spherical-shell structure has a first outer surface. The organic food-ingredient powder coating is formed on the first outer surface by injection molding.
