Code
I ran across a nice way of measuring the temperature of the CPU chip on the Raspberry Pi:
Do this: $ cat >/usr/local/bin/temperature /opt/vc/bin/vcgencmd measure_temp $ chmod u+x /usr/local/bin/temperature Then you can do this: $ temperature temp=57.3'C

Circle and Rectangle
Image made by Dylan Carlson using Python’s turtle graphics. This image is made up entirely of copies of a large rectangle rotated around one corner. Click on image to see higher resolution version.

Fun stack machine code (Python 3) posted to github in file sm.py.
Examples:
1. Simple instruction: run("1 2 add") ==> 3
2. More complicated code: run("1 2 add 2 3 add mul") ==> 15
3. New instruction: run("defprog cube dup dup mul mul /defprog 3 cube") ==> 27
4. Use variables: run("3 a sto 4 b sto a rcl square b rcl square add") ==> 25
You can also run this at the command line, e.g., python3 sm.py 1 2 add.
Verbosity is on by default, in which case you get a stack trace, e.g.,
[nano] python3 sm.py 1 2 add 3 add
=================================
code: [‘1’, ‘2’, ‘add’, ‘3’, ‘add’]
———
token: 1
stack: [1]

token: 2
stack: [1, 2]

token: add
in exop, stack: [1, 2, ‘add’]
stack: [3]
———
token: 3
stack: [3, 3]

token: add
in exop, stack: [3, 3, ‘add’]

Snowflake
Pythnon code at github. Used python3 star.py 6 3 star to produce image, which will be both displayed and stored in star3.eps. The image shown here was subsequently modified with Pixelmator, e.g., produce white-on-black image instead of black-on-white.

Fractal Cross
Pythnon code at github. Used python3 star.py 4 3 cross to produce image, which will be both displayed and stored in cross3.eps. The image shown here was subsequently altered with Pixelmator (blue overlay added)

Compositium 3
Compositium 3 consists of four superimposed copies of an image representing two plumes created by Brownian motion. The copies have been translated, flipped, and arranged to counterbalance the irregularity of the plumes with a degree of symmetry and also to fill the canvas.
The original Brownian motion image was made with a new version of Kaleidoscope, an iphone app for running simulations and procedural art animations. This version features a drop-in architecture by means of which different dynamical systems can be dropped into the app with no changes to the rendering engine.
