Point coloration distribution is between a sepia and a point cat. The "lynx point" pattern is formed by cross-breeding a colorpoint cat with a tabby cat (or breeding cats that already possess the lynx point pattern). It is characterized by a mixture of the darkening (reduced) of point coloration, with distinct tabby striping on the head, tail, and legs, and an otherwise uniform and comparatively pale body. It is an accepted pattern, in some cat registries but not others, for particular breeds, mostly Siamese-related. Lynx point coloration was also a feature of some of the foundation stock of the Siberian. Tan points
Point source fluid is the inverse of a fluid point sink (a point where fluid is removed). Whereas fluid sinks exhibit complex rapidly changing behaviour such as is seen in vortices (for example water running into a plug-hole or tornadoes generated at points where air is rising), fluid sources generally produce simple flow patterns, with stationary isotropic point sources generating an expanding sphere of new fluid. If the fluid is moving (such as wind in air or currents in water) a plume is generated from the point source. Examples: Sources of various types of pollution are often considered as point sources in
