Well, I suspect which readers will continue reading such description without a figure. So... I've made some interactive polyomino figure for illustration. They're written in Java (beta api). The coffee icon means that the page/link have one or more applets showing polyominoes. A compensatation is that you'll need Netscape 2.x to read these pages. (more info)
These pages are under rewrite. The original page contains similar info, but use my previous version of an applet to show polyomino.
By the way, this page has been accessed for
times.
You may also visit my pages on magic square. There you may find a beautiful combination of figure and numbers.
