i made a processing sketch that decodes the image (click here to try it yourself)

and i also decoded it using my G1

i just added 6 new pencil drawings to my drawings gallery

I started to write a little processing tutorial, showing how to write a great sidescrolling space shooter like in this screenshot below.

please give me a little bit of feedback and show me all the great games you make with the help of my tutorial

cropborder is a little java-tool i wrote to remove the white border of a pdf file, to make it more readable on an ebook-reader.

the white margin around the content is very usefull when printed on paper, but is really anoying on an ebook-reader because it only makes the text smaller.

to use the tool call it with

java -jar cropborder.jar [-in <input.pdf>] [-out <output.pdf>] [-f <scaling factor>] [-l <dots to move the left border>] [-d <dots to move the lower border>]

the default values for the parameter are

in.pdf for intput out.pdf for output 1.4 for the scaling factor and shift by -100, and -130 points (a point is a 1/72 inch)

the tool uses the iText library and is published under the "do whatever you like, but don't blame me if it goes boom"-Licence

i also made a project page for it

I made a processing-sketch that shows the time using colors. i made 3 stripes of colors blending into each other, each of them cycling through the hue value of the color. then i blend between the colors.

the top color shows the hour, the middle color shows the minutes and the low color the seconds. the values start at red, blend to yellow and green, and get turcise at the half of the cycle. than they blend to blue and violet and finally back to red.
