Points of Departure was a progression from Surface Tension. Both rely on distortion to create the effect.

Shapes which can be fitted together to cover a flat surface are called tessellations. Using several shapes the same, four-sided shapes can always be fitted together, even when they have a concave side.  The shapes in this afghan look like squares because they are arranged in a square grid. They have circular bases and, mathematically, circles will not fit together without leaving gaps. (See the problems we encountered with Try Angulate.)

With knitting and crochet, normal geometric rules can be ignored because the pieces will distort to look like something they are not.

These circles are fun because, even without the distortion of joining them together in a strange way, they are not flat. Each one has a little dome in the middle. The afghan reminds m a bit of bubble-wrap. You can’t pop these bubbles but you can push them to the other side ten turn it all over and start again. The bubbles also help to trap the air so it is a surprisingly warm afghan. The disadvantage is that the circles takes a little bit more time to make than flat circles would.

The pattern includes instructions for making some other domed shapes that will also fit together to create an interesting surface.
