My latest processing-sketch features some letters that are dropping from the top of the window to the bottom and form a word.

I wrote another simple and pretty useless (i mean simple, pretty and useless :-)) sketch in processing. I wanted to see how the noise function reacts so i wrote a sketch that draws plasma. Press any key to change between color and grayscale mode.

Today i managed to make a scan using my conmark L2000 3D-Scanner that looks at least similar to the object i tried to scan :-)
it's not quite what i hoped it to be yet, but at least it's a start.

I managed to use an arduino as an isp programmer for my ATTiny13. I first i tried to use the avr910 program described in this blogpost from Randall Bohn, but avrdude could not flash my hex file :-/
then i found a newer version of the code that emulates an avrisp at googlecode

Ruby provides some very interesting set operations on arrays.
given the two arrays A and B wich look like this
A = ["A", "B", "C", "D"]
B = ["C", "D", "E"]
There are three set operations we can use that union, intersection and difference.

A | B
contains all elements from both sets without doublicates. So this results in ["A", "B", "C", "D", "E"]

A - B
contains all elements from set A that are not in set B. So this results in ["A", "B"]

A & B
contains all elements that are in set A and in set B. So this results in ["C", "D"]

32 pages so far, i added another section and i finished some of the examples for the book. One example for the chapter on interaction will be a litte game. The player has to type some random letters that appear on the screen. After 20 sections the number of found letters is displayed as the score.
