Back in the studio and playing with light, water oil and brusho

This evening my class was just me and one student so while she was working I was able to play, working with ideas from yesterday’s critique. It looks like I might have found a way to make slides in which the contents of oil and water move about.... I have been working on the illimination of the rectangle of light that the slide dictates by making paper ‘masks’ for the slide edges. I have also been playing with the shape of the triptych, making it out of paper and decorating the back.
