To her right was a long oak bar, "the juice bar," one of the features that set Erehwon apart from other virtual locales. It was a Matrix construct, but it served a very real purpose. Deckers could send their icons up to the bar, where they could order "buzzers." In terms of icons, the drink icons appeared as beers, highballs, or shooters. In actuality, however, they represented small and simple utility programs that produced slight and temporary biofeedback loops in the minds of the deckers partaking. These loops produced various psychological effects— generally a mild euphoria—that partially mimicked the effects of alcohol. Although Sly had no intention of experimenting with buzzers tonight, she had to admit the concept was attractive. One could get the pleasant buzz of drinking without any hangover, and theoretically, simply abort the utility at any time to be instantly "sober" again.
