Girls und Panzer has one of my favorite premises for an anime ever. There is a high school. They have after-school clubs. One of them is tank warfare. Come on, you have to admit that's pretty awesome. Anyways, they've created a special edition vase used for Japanese flower arranging (ikebana) themed after the anime. You could say that it has quite the powerful impact!
