A rotatable reel 100 for an entertainment machine comprises a circumferential lateral surface 101 and an internal frame structure 102. The reel 100 is provided with illumination means 110. The illumination means 110 are provided in a circumferentially mounted row, the row aligned with the direction of rotation about the central axis X. The illumination means 110 are activated by an illumination control unit at frequencies related to the rotation frequency of the rotatable reel 100 about central axis X.

A room installation is provided having at least three walls, a ceiling and floor, all of which are covered in a mirrored surface. At least one transparent window allows ambient light into the room installation. A plurality of mirrored balloons are arranged within the room installation, and filled with helium, but otherwise weighted, to float substantially within a middle height of the room installation.

A camera includes a data acquisition unit, a photographing area control unit, a photographing unit and a communication unit. The data acquisition unit acquires, as photographing information, at least one of time information, information on a position of the sun, information on an angle between a sunlight and a ground, and projection information of an external projection device. The photographing condition calculation unit calculates a photographing condition based on the photographing information. The photographing area control unit controls a photographing area based on the photographing condition. The photographing unit generates an image data by photographing the photographing area. The communication unit transmits the image data to the external projection device.
