I don't know if there is an accepted name for what I'm about to describe, I've seen it called "I spy with a twist" when diagonally set. but I was thinking straight set.
You need a medium or large print fabric (or several coordinating if you prefer), then two colours, plain, tone on tone, whatever floats your boat, I just did it with sparkly fabric!
You make two different blocks, one is the snowball block, a square with triangles at each corner, use the same colour on one diagnonal and the other on the other.
The other block is partially pieced, so you sew 5 times to get 4 rectangles around a square, the opposite sides being the same colour. The rectangles are cut the same width as the squares used to make the corners in the other block.
You lay them all out so it looks like a woven lattice. Here's a picture of one I did like this for my son
