A visual display system creates various visual and audible effects from the motion of light particulate matter, such as beads. The system makes use of a variable flow air array generation device that facilitates a variable flow air array within the chamber. The device includes three or more array sections and a controller. The array sections each contribute distinct but coordinated air flows that coalesce with each other into forming the variable flow air array within the chamber. The controller controls each of the array sections. The variable flow air array generated by the device agitates, fluidizes, suspends, or floats at least some of a plurality of beads in the chamber creating a dynamic display of beads within the chamber.

Provided are an information processing apparatus, a head mounted display housing, and an information processing method capable of providing a virtual reality experience suitable for individual users. Provided is an information processing apparatus that is detachably held by a housing to be usable as a head mounted display, and that includes a display unit (306) that displays an image; a detection unit (308) that detects an indicator provided in the housing; and a control unit (302) that controls the image displayed on the display unit based on information indicated by the indicator, the information being detected by the detection unit.

A product advertisement system includes (A) a plurality of miniature three-dimensional product models, wherein each product model (i) has a bottom surface, a top surface, and a side surface extending between the top and bottom surfaces; (ii) is a scaled replica of a full-size residential or commercial appliance; and (iii) has a hollow interior configuration with an opening in the bottom surface; and (B) a base configured to retain each product model in a single position thereon.
