I don't know of any, but it's a good idea! Shabby Frabrics made an I Spy quilt tutorial that showcased a particular line of fabric. As I remember, the fabric is just really busy with a lot of pictures on it. You could probably cut that into pieces without a lot of leftover, since any cut would have likely have something good on it.
There is the possibility of printing your own on Spoonflower or something and get it spaced out the way you want and use the pictures you want.
I wonder if there are some border fabrics or panel quilts that may suit your needs better.
