Following yesterday’s experiments with the Random Pi Walk (hat tip Alex Bellos), I’ve upped the ante.  The above image is the decimal expansion of the square root of two, following the first one million digits.  The data is thanks to Stan Kerr via Project Gutenberg.  Each decimal digit 0-9 results in a change of direction of 36 degrees and, in this case, travels 3 pixels in that direction.

The resulting image is MUCH larger than the previous visualizations – click here for the full resolution version.

Random walk based on the decimal expansion of pi (from the previous post), but this time in 3d space. Created using Processing and OpenGL.

Attempting to sort by height… ended up with this instead.

The above image is the result of a Processing sketch that takes an audio file, sorts its sample values, and visualizes the current and original position of each sample.  At 44,100 samples per second, the above 10-second audio file has 441,000 arcs.  Height and line color are proportionate to the distance the line travels, otherwise the image would basically be a big block.

Still in refinement, source code forthcoming…

Visualization of the “quicksort” algorigthm, by Wikipedia user RolandH.

My first supercomputing job ran yesterday: the visualization of every possible combination of the notes of the Nokia Tune ringtone… all 6,227,020,800 of them!

Run using code written in Processing (with the help of Adam Caprez and Ashu Guru at the UNL Holland Computing Center) on the Open Science Grid of supercomputers, the result is ~311,000 image files, each with 20k permutations; the above image is a scant 3k permutations.

Very excited!

Harkins and Hall’s 1919 spiral periodic table

With literally hundreds of examples, Dr. Mark R Leach’s “Chemogenesis Web Book” on the history of the display of the periodic table.  Lots of different categories and definitely weird permutations.  Selections here from “Spiral Formulations” section.
