Currently I'm writing some gis applications at work. As a by-product I made a Desktop background image from a world map.

Today I made a little processing sketch that features some random light-streaks that are rendered in realtime. I generate the effekt by drawing 100 little glowing particles that follow a random bezier-path.

This processing-sketch features a sphere that dissolves into a 3D-particle system and explodes when you click on it.

I wrote a small processing sketch to explore circular mosaik pattern

I updated my hexagonal labyrinth sketch to generate a 3D labyrinth and exported it as stl file. Then I printed it on my 3D printer. It took a while to convert the stl file to gcode but finally something printable was generated.

So if you need a labyrinth for your next puzzle or your science experiment with ants or ... download the sketch here, generate a labyrinth, take the stl-file and print it on your makerbot or use it in your mashups.

you can also use the pre-generated stl file I used to print

Processing 1.5 is the first released version that supports the android mode in processing. So I wrote a simple monome-clone in processing to test it.

Download the complete source here if you want to try it yourself.

The sketch uses the OscP5 library to generate or react to osc-messages, but unfortenatly processing still has problems resolving external libraries in android mode. So I added the oscp5.jar to the sketch using "Add File" - works like a charm.

The sketch is far from perfect - the target address of the osc events is still hardcoded, no support for multitouch events yet, etc - but its really nice to see how fast an android app can be made with processing

This is my Archos 101 running the my monome-clone

JDBC is the java api for connecting to sql databases. Since java6, javadb - a small, simple, javabased database-engine is delivered with java. This is a small example of how to access a database with javaDB from a processing-sketch.

First you need to download the driver from the javadb download site select the "All Plattforms" package and extract derby.jar from the zip file.

Add this jar file to your processing-sketch using the "Add File..."-Item form the "Sketch"-Menu.

The following sketch creates a small database containing one table in the setup method (the "drop table ..." statement deletes the table if it already exists. If you want to pregenerate your database or keep it, remove this line.)

I took my labyrinth generator and reworked the algorithm a bit to generate hexagonal labyrinths.

Bathroom-real-estate is a very limited resource in our flat, so I designed a brush-holder that can be glued to the wall and printed it on my makerbot.

I really like how a 3D-printer helps from getting "would be nice if .." into "cool - lets try it"

you can download the brushholder openscad source or the exported brushholder stl

yesterday I made a processing-sketch to generate labyrinths. Today I made a slightly modified version to let it generate EASTER-labyrinths by placing colored eggs on the cells.

print them on a color printer and have fun while hunting the eggs
