Serpinski's gasket is named after the late Polish mathematician Wraclaw Serpinski. His gasket can be constructed by taking an equilateral triangle, dividing it into four smaller equilateral triangles, removing the centre triangle and repeating the process with each of the smaller triangles. Serpinski's gasket can also be obtained from Pascal's triangle if all the even numbers are filled in. Researchers have used the shape of Serpinski's gasket to create antennas because of its jagged form ("Practical Fractals", News and Analysis, Scientific American, July 1999).
