Here are some images from assignment 4.

The options that I did for this assignment were: multiple reflections, an interesting shaped mirror, grayscale effect applied to that mirror and a partially reflective floor in which you can see the floor texture in addition to the reflection.

The recursive reflection shows up in the triceratops mirror. The Fresnel effect doesn't work on the floor yet and the reflections are a little off there as well.
