Strawberry. Grape. Tangerine. Old iMac colors? Nope -- new Mac aromas. Treading the thin line between brilliant and bizarre is iSmell, a speaker-size device that adds a whole new dimension to your computing experience. Able to mix and match elements from a hundred-scent palette, the iSmell from DigiScents (510/208-4300, www.digiscents.com ) can produce thousands of unique odors. Savor the aroma of the coffee beans you're about to order online. Smell the spent shotgun casings -- and your opponent's fear -- as you play a scent-enhanced first-person shooter game. Due for release at the end of 2001, the Mac version of the peripheral should make its public debut at January's Consumer Electronics Show in Las Vegas. No matter how well it works, it's sure to raise a stink.
