The 10 minute block, you can see it on youtube. It literally only take 10 minutes or less. If you have a layer cake quilt fabric (40 10 inch sqaures) It's even faster. It takes only 5 10 inch squares to make one. If you made 4 10 minute blocks it would give you a 40 x 40 baby quilt and you can complete the top in under an hour. Amazing.
