Resumen:
We revisit the gravitational lensing phenomenon using a new
visualization technique. It consists in projecting the observers sky
into the source plane, what gives rise to a folded and stretched
surface. This provides a clear graphical tool to visualize some
interesting well-known effects, such as the development of multiple
images of a source, the structure of the caustic curves, the parity of
the images and their magnification as a function of the source
position.
