DFT of Geometric Matrices

Here we plot special matrices (where any element can only be 0,i,-1,-i, and 1) and the DFT of those matrices.  Click on a cell of the matrix to cycle through element values.  To change the color, select from the drop down box.  To select a larger size, find select the size then press "Reset".  The numerical value of the DFT gets annoying, so hide it by unchecking the checkbox.
