Twisted Button

The "holes" in the middle of this one reminded me of buttons. You know the sort, the large "chunky" ones that you find on coats etc.

Today's Gratitude Item: Integration (as in Calculus). Not only is this a convenient way to work out the "area under a curve", its also a good topic to teach. Had two classes of it at school today and one of my private students wanted to revise / learn it as well. Turns out that integration can be good for paying bills :)
