We consider the shuffle operation on paths and study some parameters. In the case of square lattices, shuffling with a particular periodic word (of period 2) corresponding to paperfoldings reveals some characteristic properties: closed paths remain closed; the area and perimeter double; the center of gravity moves under a 45 rotation and a cache/MiamiImageURL/B6V1G-4PYYTYC-1-2/0?wchp=dGLbVtb-zSkzk"" alt=""Click to view the MathML source"" align=""absbottom"" border=""0"" height=15 width=21> zoom factor. We also observe invariance properties for the associated Dragon curves. Moreover, replacing square lattice paths by paths involving 2kπ/N-turns, we find analogous results using more general shuffles.
