Si quieres que el cursor o puntero sea perseguido por una estela de imágenes cuyo tamaño y aspecto tu elijas sólo tienes que incluir el código adjunto en tu página en cualquier lugar entre las etiquetas <body> y </body>. Para colocar las imágenes "perseguidoras" que desees, basta con que sustituyas las partes despues de Los URLSdel código por la ruta de las imágenes que hayas elegido y definas la altura (height) y anchura (width) en píxeles de las mismas. El resto del código puedes dejarlo igual.

El efecto que se consigue es el que puedes ver en esta misma página. Nosotros hemos usado de ejemplo unas estrellas, pero tu puedes emplear tu propio logotipo, o cualquier imagen que se te ocurra y del tamaño que elijas (animales, rayos, etc...).


Código a copiar:
