A multi-user animation process receives input from multiple remote clients to manipulate avatars through a modeled 3-D environment. According to an embodiment, the present invention provides a method of reproducing main data and additional data. Preferably, there are a plurality of MQWSs, which may be arranged in a serial stack or may be arranged in a plane parallel to the MQWS layers, with light passed from one MQWS to the next via prisms. The color of the sub-pixel of the pixel array is identical to that of another sub-pixel of another pixel array adjacent to the pixel array. The extrusion resistant ring in combination with an elastomeric diaphragm provides a high pressure seal for down-hole oil drilling apparatus. The compensation circuitry, which includes serially coupled capacitive and resistive circuit elements, introduces a high frequency zero to cancel one of the high frequency complex poles introduced by the Miller feedback capacitor connection.
