Yes, it's a degree of interest interaction. There have been various attempts to implement this DOI idea since it came out, and I'm pointing to this one as a rather novel implementation, that may overcome some of the usability issues seen with hyperbolic trees, etc.

I would definitely test its usability with a taxonomic tree data set and some "normal folk" before advocating it as the ultimate solution for an EOL project. Denise Green and I did these types of usability tests on three interactive tree presentations available in 2005, providing something of a baseline against which this particular interaction style might be judged.

    This begs the question:  has this style of user-interface failed
    to catch on
    more widely because of:

    1) Technological limitations;
    2) Insufficient creativity and inspiration; or
    3) Insufficient usability?

    I'm tempted to eliminate #3 on the grounds that I don't think this
    style of
    UI has been widespread enough to have been subjected to, and then
    failed,
    some sort of usability meta-experiment.

    This is not to say that it won't ultimately fail such a
    meta-experiment --
    just that it hasn't really had a chance to fail it yet.
