These big forms are all about symmetries and pattern. There is usually a symmetric pattern in making them as well. Check out the videos, some of them show the making of big forms with Conectaballs.
These and many other shapes that can be made with Conectaballs follow the same pattern — three lines (edges) meet at each connection. There are four balls along each line of the shape, two corner balls and two line balls. Each Conectaballs string has eight balls. The two balls at the end of a string become corners of the shape. The other six balls become three lines of the shape.
Get started with Conectaballs. Make these shapes and try your own variations. See what you will come up with and have fun!
