Interstellar clouds with high Alfv'en velocity act as concave lenses to diverge the MHD waves, while those with slow \alf velocity act as convex lenses to converge the waves to the focal points.By combination of various types of clouds and fluctuations with different Alfv'en velocities, sizes, or wavelengths, the MHD-wave shells attain various morphological structures, exhibiting filaments, arcs, loops, holes, and focal strings, somehow mimicking old and deformed SNRs.
