I shot some pattern pictures out on Swiss fields during these (rainy) days, my favorite being this intense blue forget-me-not flowers (click it to download a full version).In this wide-angle view there is only one flower on focus, can you find it? 
What I love in this view are the flower stages of development: a kind of same-same but different. From purple to blue-and-yellow to blue-and-white, as summarized in the table below. This change is due to a pH shift in the cells of petals.
