for the flat shading use a "parallel" light source (although just
placing it distant enough probably works too). Relative brightness of
left / right / top can be tweaked with angle of incoming light. E.g.

#default {finish {ambient 0}}

global_settings
{
   assumed_gamma 1.0
}

camera
{
   orthographic
   location  <0.0, 4.0, -5.0>
   look_at   <0.0, 1.0,  0.0>
   angle 90
}


light_source
{
   <-15,  40, -30>
   color rgb 2
   parallel
}

box
{
   0,2
   pigment {color rgb 1}
   translate -<1,0,1>
   rotate 45*y
}
