A possible random Delaunay triangulation (screenshot from the applet)

Just a link to an instructive applet on Voronoi diagrams and Delaunay triangulations as appearing in computational geometry.

From the site:

• The Voronoi Diagram has the property that for each site (clicked with the mouse) every point in the region around that site is closer to that site than to any of the other sites.
• The Delaunay Triangulation is the geometric dual of the Voronoi Diagram. Alternately, it can be defined as a triangulation of the sites with the additional property that for each triangle of the triangulation, the circumcircle of that triangle is empty of all other sites.

In the above applet the user can switch between the two constructions.

->Another Delaunay triangulation application (java webstart) from Markus.

Today I am trying to make sense of the dynamics of advertizing. I am fully aware that this will end up in a rather naive attempt, but whatever – the customer has a right to think. This going to be more an essay then just a blog post.

This weekend there are Tenso days in Berlin, which is a festival for contemporary chamber choir.

Just what seems to be a nice book:

The idea behind bastard was to bring together photographers, writers, illustrators, graphic designers, musicians and typographers to create a solid and unique book that also functions as a work of art.

Today I am digging out a historical milestone in mathematical visualization.

I am currently breaking my head over John Maeda’s Bermuda quadrilateral. Is it as simple as that?

When Matthew Barney spoke on saturday (see last post) about screens in rooms and the attraction they emanate, I was immediately getting this eerie video by Guthrie Lonergan in my head. It displays empty work places/home entertainment centers, fake and cheap strings and the empty virtual world behind the screen.

It was posted last friday on rhizome (via Tom Moody) by Marisa Olson.

Yesterday the exhibition “All in the Present Must Be Transformed” featuring the artists Matthew Barney and Joseph Beuys opened with an interview with Matthew Barney at the Deutsche Guggenheim in Berlin.

A conference in Luzern/Lucerne in 2007 about Consciousness and Quantumcomputers.
The announcement mentions Anton Zeillinger (wikipedia link) and Roger Penrose (wikipedia link) and the Dalai Lama in their intro, but unfortunately as it seems neither of them is among the speakers..:)..but whatsoever — there are still enough interesting speakers and it is an important topic to discuss.

the gallery has a torus logo!

In my previous post I wrote about an experiment of looped sound. Today’s post is about an experiment with “looped” ( i.e. periodic) light…rather known under the term strobe light.
