SHARON STONE'S SCAR

Her uncrossed legs, apparently, aren't the only thing people gawked at in Basic Instinct. This sparsely designed site features musings on an alleged -- and as-yet-unexplained -- scar on Stone's neck. The screen- grab tour of the Stone mystique features escalating circumstantial evidence of the gash's existence. Whether it's fact or fiction, the site's intro best explains why this is no ordinary boo-boo: ''It almost looks as if she's been beheaded...or had routine head-transplant surgery.'' That last theory might explain Sphere.
