Positive/Negative blocks

I am this month Queen Bee in the Bee White Black. As per the name we are making blocks with black and white fabrics. As usual when it is my turn, I change ideas about what I want to make quicker than I type it! But when I saw Amy Ellis' Digital Pinwheels quilt from her new book Modern Neutrals, I really like the design and thought it would look good in graphic fabric (hope I am right here!) So last week, I cut A LOT of black and white, white and black, plain white and plain black fabric to try out fabric combination. I first thought of having black on white for the pinwheel and white on black for the background but it looked too busy and the design was almost lost. So I made a block with a black pinwheel and plain white background (Makower white) that is the Positive

and because I hate wasting fabric and I had cut some black on white fabric too, I decided to try a white pinwheel on a black background, my Negative block

Of course Amy's quilt is a lot more subtle with the lovely neutrals she has used, mine is much more graphic.
I have now sent my packages for my fellow bees to make me similar blocks. I can't wait to get them back! I am really curious to see what this quilt will look like once finished. I am thinking of using a red binding on it. But I'll have to see once all the blocks are together!
And when you mix the Positive and Negative block this is what you have:
