Boy-meets-girl gets more complicated all the time. Jeff Aydelette, a 29-year-old native of North Carolina, hopes to get rich with a computerized match system he calls Selectrocution that allows strangers at bars and discos to find out who would like to meet whom. The concept seems confusing at first, but essentially it's a sorting system. Here's how it works: Men and women wear large initials on their lapels, and in the course of an evening court each other by sending messages via an electronic display panel above the dance floor that is operated by a keyboard unit. For example, BX might send a message to DM that he likes her dancing style. And DM might then send a message in return to BX that she likes his looks. Then players send their five favorite choices through a terminal to a computer in Rockville which sorts the whole thing out and prints the results on scorecards. For example: suppose BX says he'd like to meet CK, BJ, AR, LL and DM, and meanwhile DM says she'd like to meet SP, BH, LK, DF and BX. The computer matches up the choices, culling through the thousands of possibilities, and lets DM and BX know on a scorecard that they both want to meet. The unlucky players not chosen by anyone are "selectrocuted." The winners get to meet the person they've been sending coy messages to all night. Aydelette leases the game to bars in North Carolina, Maryland (in the Baltimore area) and Virginia (at Studio 50 in Falls Church and the lounge of the Ramada Inn on Seminary Road in Alexandria). See how easy it is to fall in love? CAPTION: Picture, no caption
