OK, I was (*gasp*) without the internet most of last week, so I worked on
this scene too long. Anyway, here's my serve-return:

#default {finish {ambient 0}}

camera {

}

 area_light x*2,y*2,25,25 circular  orient  adaptive 0
}


plane {
 y, 0
 pigment {checker color rgb 1, color rgb 0 scale 2}
 finish {specular 1 reflection 1/3 diffuse 1}
}
