What is claimed is: 1. An appliance comprising: an ice maker configured to make ice; an ice storage bin configured to store ice made by the ice maker; a dispenser including an ice dispensing chute; an ice processing device configured to process ice in at least two shapes, the ice processing device including an outlet configured allow ice processed by the ice processing device to enter the ice dispensing chute; a user input device configured to receive a selection of a shape of ice the user desires to dispense, the desired shape of ice corresponding to one of the at least two shapes; and a controller configured to control the ice processing device to process ice in the desired shape of ice to allow dispensing of the desired shape of ice by the dispenser, wherein the ice processing device includes a rotary blade that has a rotary shaft arranged to be perpendicular to a direction in which ice cubes enter an area occupied by the ice processing device, wherein the ice processing device includes a fixed blade that has a blade unit that is configured to cut ice cubes and that is arranged to face ice cubes dropping into the area occupied by the ice processing device such that at least some ice cubes dropping into the area occupied by the ice processing device fall into the blade unit of the fixed blade based on the force of gravity unless guided by the rotary blade to bypass the fixed blade, wherein the controller is configured to control the ice processing device to rotate the rotary blade in a first direction at a first speed to process ice in the first shape, and wherein the controller is configured to control the ice processing device to rotate the rotary blade in a second direction at a second speed to process ice in the second shape that is different than the first shape, the second direction being opposite the first direction and the second speed being faster than the first speed. 2. The appliance as claimed in claim 1, wherein: the controller is configured to control a direction of rotation and a speed of rotation of the rotary blade to process ice in the desired shape of ice. 3. The appliance as claimed in claim 2, wherein the rotary blade includes a relatively sharp side, a relatively dull side, and at least one protrusion extending from and positioned on a circumferential surface of an end of the rotary blade. 4. The appliance as claimed in claim 1, wherein the controller is configured to control the rotary blade to rotate at a speed sufficient to ensure a typical ice piece contacts an outer circumferential surface of the rotary blade. 5. The appliance as claimed in claim 1, wherein the user input device is configured to receive a selection of one of cubed ice, sliced ice, and grinded ice. 6. An appliance comprising: an ice maker configured to make ice; an ice storage bin configured to store ice made by the ice maker; a dispenser including an ice dispensing chute; an ice processing device configured to process ice in at least two shapes, the ice processing device including an outlet configured to allow ice processed by the ice processing device to enter the ice dispensing chute, the ice processing device comprising: a fixed blade, and a rotary blade configured to rotate in a first direction to process ice in a first shape and rotate in a second direction that is opposite the first direction to process ice in a second shape that is different than the first shape; a user input device configured to receive a selection of a shape of ice the user desires to dispense, the desired shape of ice corresponding to one of the at least two shapes; and a controller configured to control the ice processing device to process ice in the desired shape of ice to allow dispensing of the desired shape of ice by the dispenser, wherein the ice storage bin includes an inclined surface configured to guide, by force of gravity, an ice cube in the ice storage bin from above the ice processing device to drop into an area occupied by the ice processing device, wherein the controller is configured to: in response to the desired shape of ice being the first shape, rotate the rotary blade in the first direction at a first speed to cause the rotary blade to guide the ice cube dropped into the area occupied by the ice processing device through the outlet without contacting the fixed blade, and in response to the desired shape of ice being the second shape, rotate the rotary blade in the second direction at a second speed to cause the rotary blade to guide the ice cube dropped into the area occupied by the ice processing device toward the fixed blade to cut the ice cube into two or more pieces before passing through the outlet the second speed being faster than the first speed, wherein a rotary shaft of the rotary blade is arranged to be perpendicular to a direction in which ice cubes enter the area occupied by the ice processing device, and wherein the fixed blade includes a blade unit that is configured to cut ice cubes and that is arranged to face ice cubes dropping into the area occupied by the ice processing device such that at least some ice cubes dropping into the area occupied by the ice processing device fall into the blade unit of the fixed blade based on the force of gravity unless guided by the rotary blade to bypass the fixed blade. 7. The appliance as claimed in claim 6, wherein the first shape is a cubed shape, the second shape is a sliced shape, and the user input device is configured to receive a selection of one of cubed ice and sliced ice. 8. The appliance as claimed in claim 6, wherein the rotary blade includes a relatively sharp side and a relatively dull side. 9. The appliance as claimed in claim 8, wherein the rotary blade is configured such that the relatively dull side of the rotary blade contacts the ice cube dropped into the area occupied by the ice processing device when the rotary blade is rotated in the first direction and the relatively sharp side of the rotary blade contacts the ice cube dropped into the area occupied by the ice processing device when the rotary blade is rotated in the second direction. 10. The appliance as claimed in claim 6, wherein the ice storage bin includes multiple inclined surfaces configured to guide, by force of gravity, ice cubes in the ice storage bin toward the ice processing device. 11. The appliance as claimed in claim 10, wherein the multiple inclined surfaces include inclined surfaces positioned at opposite sides of the ice storage bin. 12. The appliance as claimed in claim 6, wherein the rotary blade extends from the rotary shaft to an inner circumference surface of the ice storage bin. 13. The appliance as claimed in claim 6, wherein the rotary blade extends from the rotary shaft to an inner circumference surface of the ice storage bin.
