I've recently been working on a design of an interface and have been doing some prototyping in d3 to support that effort. One of the effects we are considering is a 'fisheye' swell when mousing over a set of options.
I put together a small demo of what this would look like in practice. It is a work in progress for anything that may become useful but I like the idea so far.
You can find the code on github: fisheye
