In one embodiment, a method includes displaying one or more objects on a display device and receiving a user input corresponding to a movement along the display device. The method further includes determining a motion of each of the one or more objects on the display device. The determined motion corresponds to the user input and includes: a first motion that includes a translation of each of the objects along a particular path across at least a portion of the display device and a second motion that includes a decaying oscillatory motion of each of the objects where an amplitude of the decaying oscillatory motion decreases with time. The method also includes applying the determined motion to the one or more objects displayed on the display device.
