Have you ever tried this?
I ran an art session at a school this week, trying this activity out with the children. Not only is this cool, but the resulting shape suggests it could be used in many ideas. I showed one of these to the pupils:
There were some interesting ideas from the kids, ranging from combining several curves to make a start, a hat, an eye, and so on.
I’d be really interested to see any other arty ideas you could use the curve in. Do please put them on the comments on the website.
