a 2D audio visualizer script for Blender 2.5+ (v0.3)
# To use this script, you must first change a few things.
# First, you'll want to change the filepath for the sound file.
# This is on line 76. Second, you might want to change the materials or the settings.
# To render this, you'll need to set the background color, enable Only Render on the display window, and render it with OpenGL (it's much faster and most optimal for 2D renders.)
# LICENSE = wtfpl
# VERSION = 0.3

An animated normalized stacked barchart.

This is an animated variation of mbostock's normalized stacked barchart. When you click on a block, that block is sent to the bottom of the stack and the bars are reordered by decreasing height of that block. This allows you to compare any value in the stacks with a common baseline, eliminating a common criticism of stacked barcharts.

Fun with C++: implementing a pub/sub scenario using std::bind and other standard facilities. The approach is pretty similar to the well known .NET event mechanism.
#include <iostream>
#include <map>
#include <algorithm>
#include <functional>
#include <memory>
using namespace std;
class EventArgs {
