A painting in a painting

I was trying to think of a challenging project for my Painting/Sculpture students. Mostly I was trying to think of a project to slow them down.  They are making quality work, but at a feverish pace and I am running out of ideas. 

So about 2 weeks ago I had this thought,  what about painting a famous work of art in the style of another famous artist??  At first I think they thought I was crazy, but then they started to get into the project and while not all of them are done the first few are pretty good.
