Well.............if u are a seafood restaurant and wanted to catch fish.........u might use a net......

"Caught in a Dual Net," by Radmila Sazdanovic, The George Washington University, Washington, DC (2008) Digital print, 16" x 16". "This computer graphic represents three superimposed tessellations. The edges of a tessellation (6,6,7) are hidden below two nets consisting of tessellations (7,7,7) and (3,3,3,3,3,3,3), both dual to the original one. My inspiration stems from the rich geometric structures found in tessellations of the hyperbolic plane. Mathematical objects can be manipulated in many ways (superimposing, dualizing, breaking symmetry) to create aesthetically pleasing computer graphics brought to life by the unusual combination of colors." --- Radmila Sazdanovic, Graduate student, The George Washington University, Washington, DC
