`Peano' - Fully Two-dimensional Dasher

Peano Curve - capable of using both dimensions as information sources.
David MacKay

The idea is to embed the real line from 0 to 1 in two dimensions by mapping it onto a Peano curve. (For those who care about names, I'm told the particular Peano curve shown here is a Hilbert curve.)

As an illustration of the potential benefits, the following image compares the regular one-dimensional-dasher view of an English bigram model (left) with the Peano view (right). Many more low-probability strings are visible. Peano-dasher makes better use of screen real-estate. Whether Peano-dasher will be useable remains to be seen.
