A cool tool can be any book, gadget, software, video, map, hardware, material, or website that is tried and true. All reviews on this site are written by readers who have actually used the tool and others like it. Items can be either old or new as long as they are wonderful. We post things we like and ignore the rest. Suggestions for tools much better than what is recommended here are always wanted.

This is by far the best guide ever written for designing games. All kinds of games, simple and traditional, but of course video games, too. This fat book is packed with practical, comprehensive, imaginative, deep, and broad lessons. Every page contained amazing insights for me. The more I read and re-read, the more important I ranked this work. I now view it as not just about designing games, but one of the best guides for designing anything that demands complex interaction. My 13-year-old son, who, like most 13-year-olds, dreams of designing games, has been devouring its 470 pages, telling me, “You’ve got to read this, Dad!” It’s that kind of book: You begin to imagine your life as a game, and how you might tweak its design. Author Jesse Schell offers 100 “lenses” through which you can view your game, and each one is a useful maxim for any assignment. — KK

Silly putty — even the newer varieties like the thinking putty here — has long been sold in small amounts in the classic plastic egg. But this stuff is best enjoyed in bulk. The technical name of this now generic substance is Dow Corning Dilatant Compound 3179. Five pounds of it is…. well, pretty silly. Ten pounds of the stuff is enough to transfer a whole page of comics, or to make a humungous superball, or to lighten up the dour faces in a boardroom after being parcelled out. The surprise for our family has been never ending amusement of watching a huge ball of this compound slowly melt over whatever you set it on, like the blob from outer space. Hand out some at your next birthday party. Don’t ask why. — KK
