Oh yes ... I expirienced this effect myself some time ago when I placed some
candles next the window.
It was a nice effect, especially when you calculated the focal blur for the
reflected objects, but still have the original objects visible in the
viewport (and you use some HQ fb-params)

I asked myself what they are reflecting there, but I decided it must be some

But now, knowing of the mirror, the shadows in their relation to the
lightsources are making sense

1152x864 ?

But if you open the sources I would render it myself in 2400x1800 and
V(ery)HQ fb-params ;)
