The European new comer Sixpli is a visualization design tool developed for use with del.icio.us. Users can navigate through their own tags in an interactive network which employs different imaging methods including elastic net 3D, 2D and circles. It's pretty imaginative, eye bending stuff—the creators are influenced by the likes of Borges, Turing and Godel. The graphics aren't simply decorative, Ikea-esque things, they have a structure and purpose—communication. The way 6pli interprets Del.icio.us tags is meant as an open commentary of sorts. Its aim is to allow people to discern and enjoy different organizational forms, to achieve a new sort of navigational experience. To take part in Sixpli you'll need a del.icio.us account. Registration with Sixpli is completely free.
