nice!  but what really spoils is the fact that the normals on the wall are not
visible under the flat shadows.  You'll learn in time all the craze behing
Global Illumination that took the CG world by storm... available in povray as
radiosity...

yes, in real life there's always some glueing material between sharp edges or
some non-linear, assymetric distortions... very hard on SDL, specially with
functions and isosurfaces...

I wish there could be a way to do straightforward CSG with primitive shapes and
specify some glueing threshold...
