         7 . The device of  claim 1 , wherein the cooling plate comprises one or more of: a geometric circular symmetry, other than in a given area that is off-center from the center-of-rotation of the cooling plate; and the geometric circular symmetry with mass asymmetry, so that the center-of-mass is different from a geometric center of the cooling plate. 
     
     
         8 . The device of  claim 1 , wherein the hub is flexible. 
     
     
         9 . A system comprising:
 a device comprising: a light emitting material; a cooling plate configured to cool the light emitting material, the cooling plate comprising a center-of-mass that is different from the center-of-rotation of the cooling plate; and, a hub located at the center-of-rotation of the cooling plate;   a shaft configured to mate with the hub; and,   a motor configured to rotate the shaft so that the hub and cooling plate rotate in response to rotation of the shaft, the center-of-mass of the cooling plate being off-centre causing the cooling plate to one or more of vibrate and oscillate when rotated.   
     
     
         10 . The system of  claim 9 , wherein at least a portion of the hub is flexible. 
     
     
         11 . The system of  claim 9 , further comprising a respective hub connecting the shaft to the motor, at least a portion of the respective hub being flexible. 
     
     
         12 . The system of  claim 9 , further comprising a base, the motor mounted to the base, at least a portion of the base being flexible so that the motor is isolated from the base when the cooling plate is rotated. 
     
     
         13 . The system of  claim 9 , further comprising: a bearing for supporting the shaft; and a base, the bearing one or more of comprising the base and mounted on the base, at least a portion of the base being flexible so that the shaft is isolated when the cooling plate is rotated. 
     
     
         14 . The system of  claim 9 , wherein the cooling plate comprises one or more of:
 a weight that is off-center from the center-of-rotation of the cooling plate;   a cut-out that is off-center from the center-of-rotation of the cooling plate;   an outer edge that is one or more of: lacking circular symmetry; and configured to shift the center-of-mass from the center-of-rotation of the cooling plate;   the center-of-rotation being different from a geometric center of the cooling plate;   one or more of: at least one side that is tapered; and sides that are not parallel; and,   one or more of: a geometric circular symmetry, other than in a given area that is off-center from the center-of-rotation of the cooling plate; and the geometric circular symmetry with mass asymmetry, so that the center-of-mass is different from a geometric center of the cooling plate.   
     
     
         15 . A system comprising:
 a device comprising: a light emitting material; a cooling plate configured to cool the light emitting material; and, a hub located at the center-of-rotation of the cooling plate;   a shaft configured to mate with the hub; and,   a motor configured to rotate the shaft so that the hub and cooling plate rotate in response to rotation of the shaft,   one or more of the shaft and a rotational portion of the motor configured to one or more of vibrate and oscillate when rotated, which in turn causes the device to one or more of vibrate and oscillate when rotated.   
     
     
         16 . The system of  claim 15 , wherein a center-of-mass of one or more the shaft and the rotational portion of the motor is located off of a respective rotational axis.
