The Powder Toy has become one of the most popular toys this year. It's also received great reviews by those who have played the game. Here are a review of the toy, as well as some information on how to get it free with a purchase of the game.
A challenging and fun physics-based puzzle game that lets you experience using several different materials in a variety of environments. The Powder Toy is actually a physics sandbox application for Mac OS X, which gives you the opportunity to build and blow up different structures and watch the effects on your screen. The great thing about using the powder Toy is that it works perfectly in both the "Real" version and the "Rendered" version of the software. So if you're using the "Real" version of the software, then you can just drag and drop all your stuff into the virtual space and watch the destruction it causes.
The second major difference between the real version and the "Rendered" version of the application is the way that the levels are generated. With the "Real" version, you actually get to see the structure as it is being built, which means you are forced to follow certain patterns. This isn't really necessary in the case of the "Rendered" version, since the structures are all pre-built. You can still create whatever structures you want though, and you'll be forced to follow certain guidelines and follow a prescribed path through the levels. The main difference in the way the structures are generated in the two versions is that the generated structures in the "Real" version actually follow some basic scientific principles of nature. So while you're playing the game, you'll learn a little bit more about some of the basic properties of real-life objects, as well as some interesting properties of the various solid and liquid particles that make up the structures you are building.
