Are you ready for the age of stero-optic interaction? Larry McCurdy of Silver Spring is betting his house and savings that his Eyephones will be the next big thing in the music business. Eyephones are the Me Generation's logical conclusion to the color organs of the '60s and disco light shows of the '70s. Eyephones, which effectively shut out outside light sources, consist of interchangeable color chip slides and tiny flashing lights that are activated by plugging into a stero sound source. "It's the same principle [as color organs] with more sophisticated electronics to show the full dynamic range of the music," says McCurdy, who left his job as a clinical psychologist at the University of the District of Columbia six years ago after getting a second degree in music.

When he's not teaching, McCurdy is in his basement, putting together the Eyephone from 30 components. "That's how you have to start," he says. "I don't have a factory yet." He's just finished his first production run of 1,000, of which only the lenses are still handmade. McCurdy toyed with the idea of Eyephones for more than a decade until some musician friends said, "Hey, you ought to do something with this.' So I got on it." By adding headphones, one can easily enter a powerfully solitary musical-visual universe; the glases, however, are not recommended in conjunction with the Sony Walkman -- they're best suited to the safety of immobile home listening. There are also instructions on how to manufacture one's own color chip lenses. Eyephones are currently available only by mail order ($29.95 to P.O. 6566, Silver Spring, Md. 20906). The kit comes with two sets of lenses and a phono plug.
