5x5 Dots Cube in Checkerboard Cube

This is a variant of the common Cube In Cube pattern in which the inner cube and outer cube are also depicting common patterns Dots and Checkerboard.

I tried to invert it into a Checkerboard Cube in Dots Cube,
as shown in the smaller picture at right. I don't think it worked as well, but it's still visually interesting . . . and an entertaining challenge to construct.
