A display control method includes: obtaining a position of an object which is arranged in an area when receiving an input; determining, in accordance with the position of the object, a first display position of at least a first image between the first image and a second image in a display area of a display device adjacent to the area; displaying the first image and the second image on the display device; and changing, after receiving the input, the first display position of the first image in accordance with a change in a position of the object in the area without changing a second display position of the second image.

A room installation including: a room having at least one wall, a ceiling, and a floor, each of which is at least partially covered by a mirrored surface; at least one transparent window to permit ambient light into the room; and a first plurality of mirrored balloons arranged within the room, and filled with a mixture of helium and another gas, the mixture configured to float the balloons of the first plurality of balloons substantially within a middle height of the room; and a plurality of vents to circulate and move the balloons of the first plurality of balloons in a designated pattern within the room.

A video is superimposed on an object in order that the object will be perceived as if the object were given a motion. This video is a video including a luminance motion component corresponding to a motion given to the object.

Methods and systems are described for an animated artificial water surface. A sheet of material having a glossy surface includes a three-dimensional pattern of waves extending along horizontal dimensions of the sheet. The waves have a scale-model height profile. A drive may be coupled to the sheet. The drive may be operable to move at least a portion of the sheet continuously and at a constant speed in one direction relative to the horizontal dimensions of the sheet wherein the waves model an animated water surface.
