just finish my research on how to make a raw html5 version out of my new logo. must say: html5 is bad ass! to get the “multiply” effect in html5 working (used in photoshop for the 3 layers) i had to render each layer “offscreen” by using a renderToCanvas

Voronoi Images

Using voronoi tessellation on random points as a surface for images. From here you could distribute the points in a more meaningfull way e.g. using t-SNE or d3.layout.force()

Points on concentrical ring pattern

This example shows the placement of a preset number of points (i) in a concentrical ring pattern. The amount of points from one ring to the next forms an arithmetic progression, whose constant difference („more“) can be varied. By inverting the formula for arithmetic series the necessary number of rings ist calculated for a given amount of points. Afterward the points are arranged equally spaced in the ring pattern.

Local Variables

In response to mbostock's block: Local Variables and the Tweet I implemented a little variation having a .local(name[, value) method you can use on selections.

On set, the value is stored on the given element:

element.local("foo", value);

On get, the value is retrieved from given element, or the nearest ancestor that defines it:

var value = element.local("foo");

You can’t perform that action at this time.
