Hack 43. Waste Time with Toys and Games
Amuse and inspire yourself with these decorative inventions made by bored minds.
Not everything's about substance. Sometimes, you just want to be entertained. This hack describes a few such things. Calling them fluff would be unkind, though; there's a fair bit of talent, imagination and effort at work here. Most of them won't get you a pay raise, though.
4.12.1. Messing Around with Games
Any computing environment worth its salt will eventually be able to play Tetris, or at least adventur. Firefox is no different. With lots of scripting and display technology, it's no surprise that simple games are knocking on the door. Of course, the biggest game you can play with Firefox is called "Where's that web page I forgot about?"

22.214.171.124 Card games
The Card Games extension provides dozens of single-person card games if you happen to be snowed in over winter. Figure 4-23 shows an example of a game in progress.

126.96.36.199 Console games
It's also possible to play simple 2 1/2 D console games from the 80s and 90s. Dynamic HTML (and Dynamic XUL) provide a fast enough basis for the required sprites. To play these games, you don't even need an extension. Just visit the MozDev Games web page (http://games.mozdev.org). You can run the games online by clicking their links, or you can download the games pages to your laptop and open them whenever you want. Figure 4-24 shows Xultris, a Tetris-like game.

4.12.2. Stretching Your Wings with Gestures and Pie Menus
Pie menus aren't seen much in desktop applications, but they're common in games, ever since they were made popular in fantasy console games (change from sword to potion!). Pie menus link a mouse movement to a context menu in a way that offers fast selection. Such things are innovative enough to get you a job at Microsoft.
The easyGestures extension presents a fully customizable pie menu for your enjoyment. Figure 4-25 illustrates the default set of options.

The easyGestures extension is highly configurable; just double-click it in the Extensions Manager window.
Of all the Firefox extensions, gesture extensions probably sit least well with each other. By all means, try out the many excellent alternatives, such as Mouse Gestures and Radial Context, but it's probably better to have only one installed at any given time.
