Freebie: Paginación en CSS con jQuery

Kasper es un diseñador que a través de su sitio web, Design it & Code it, regala freebies o recursos webs para desarrolladores. Esta vez ha lanzado un paginador hecho en CSS y jQuery que realmente tiene un efecto muy interesante y que se puede usar tanto en proyectos personales como en comerciales.

Acá mismo se puede ver un ejemplo y el mismo código para que funcione. A continuación, en el resto del post, el código reproducido.
