Russian Dolls

I have been looking at russian dolls which has given me a idea which i feel with work really well. As in russian dolls, they have dolls inside of dolls which follow a similar pattern. I have thought about shapes inside of shapes.
As i have been creating 3D shapes such as cubes etc. I have thought about creating a cube with a pattern cut into it, then following the same pattern and cube size it down to fit inside the original cube. Then i will continue this process until i have a few cubes inside cubes with the same pattern cut out.
I will also try adding colour to the cubes inside the cubes so there will be colours inside of colours aswel as shapes.
