The new Nintendo video game, Legend of Zelda: Ocarina of Time, is on pace to become one of the best-selling video games ever. And its popularity seems to have spawned another craze -- demand for real ocarinas, those flute-like musical instruments that look like sweet potatoes with finger holes.

In the video game, its elfin hero, Link, travels through time and the magical world of Hyrule, doing battle with his nemesis, Ganondorf, to save Princess Zelda. Playing his ocarina transports Link through time and space.

Many Nintendo fans are transporting themselves on the Web in search of their own ocarinas. Anita Feng, an artisan in Issaquah, Wash., who has been making traditional-style ceramic ocarinas for 25 years, has seen her business more than double to about 60 handmade instruments a month, since the Nintendo game was released in November.

''Right now, about three-fourths of my business is from people who played the game,'' said Ms. Feng, who operates the Anita's Ocarinas site (www.scn.org/bg599). She said she received 5 to 10 orders daily, primarily for the 10-hole ocarinas, like the one played by Luke.
