After the teaser on Friday (see Deep zooming a large 2D tree) I've put a live demo of my experiments with viewing a large tree online at: http://iphylo.org/~rpage/deeptree/ The first example (Experiment 1) is the NCBI classification for frogs: Simple deep tree viewer from Roderic Page on Vimeo.

Here's a quick demo of a 2D large tree viewer that I'm working on. The aim is to provide a simple way to view and navigate very large trees (such as the NCBI classification) in a web browser using just HTML and Javascript. At the moment this is simply a viewer, but the goal is to add the ability to show "tracks" like a genome browser.
