An apparatus creating a flickering flame effect. The unpulped fiber bundles have a modulus of elasticity of about 2-5106 psi and a chopped fiber length of about 25 mm. After that, the sealing member is cured, and the resin is heated to be vaporized so that a void is formed between a covered portion in the surface of the sensor chip, which is covered by the sealing member, and the sealing member. Sporting-relevant measurements can be computed based on the stored three-dimensional image data. A turntable sensor coupled to the base measures the rotation of the turntable, where the turntable sensor outputs turntable data indicative of the rotation to the host computer.
