Several projects have been keeping me busy, but I've nonetheless been able to find some sites I hope you'll find are worth exploring:

* Dr. Arthur Benjamin, whom I've mentioned on this blog before, has a new book that is scheduled to be released on August 8th, 2006. The tenative titles are "Think Like a Math Genius" or "Secrets of Mental Math". If you're familiar with, and fascinated with, Dr. Benjamin's work, you'll be glad to know about these books. If you're not familiar with his work, check out the above links.

* I've found another great Magic Square Page to add to the growing list of magic square sites here on Grey Matters. This site is by Harvey Heinz, whose full site is worth checking out (assuming your mind hasn't been too scrambled by the magic squares section).

* Speaking of magic squares, one of the projects I've been busy with is adding a line of magic square-related clothing to the Grey Matters Online Store. The two magic squares available there now are a magic square that still works when rotated 180 degrees, and a semi-magic square that also functions as a Knight's Tour!
