For this assignment, I want to draw a simple star using Net Logo. Using the same star, I want to explore the formation of abstract form of calculated artworks - from chaos to order then to order in chaos
The 1st work deals with the exploration of abstract artwork using algorithmic machine, inspired by Jackson Pollock's painting! 
the source file
The 2nd work explores an orderly rows of signals, inspired by TV signals the source file
The 3rd work is my attempt to combine the two earlier ideas and explore the idea of order in chaos - you might also say a merger between art and technology the source file

I decided to develop the project further into an actual art project that I might have in mind. What you see here is just a working model of the actual installation that will required active participation from audience moving through the "physical installed" space, please refer to the diagram for further details on the installation.
Please pay attention to the dynamic flow of the sound and how it interacts with the speed and direction of the flickering media waves. In the actual installation, this is how it would work:
(Pls refer the diagram as you read this)
DIRECTION: controlled by the direction of the movemements by audience across the projection.
SPEED: controlled by the amount of participants that is entering the projected space.
COLOR CHOICE: decided by the external factors from the installed space, such as humidity, noise level and etc.
CONCEPT
The artwork is formulated by extending/merging several ideas that I have formulated as part of my programming class with Prof. Ralph Abraham, the concepts are (in no particular order):
twitter
flickr
facebook
