I’ve been playing with polyominoes and other recreational math topics for quite a while, and sharing my results on an email list, and on my own website. It has occurred to me that this is the 21st century, and I should get a public blog for this material. Also, since I am now selling puzzles that I’ve designed and made, having a blog may, I hope, be a way of generating interest in them so that I can make and sell more.
Other subjects that I judge may be interesting to the same sorts of people who are into recreational math, (like interactive fiction writing, which I’ve been meaning to get back into) may come up here too. We’ll just have to see where this leads.
