You didn't come into this world.You came out of it,
like a wave from ocean. You are not a stranger here.
Alan Watts

There is a fact that everything evolving from craft process.We first create our idea from craft materials as a craft way and
with digitalization it becomes more based on computers.Becoming computers more reachable and also digitalization we start
to prefer directly digital tools to create our ideas.According to this idea this projects aim is to create nature reflections inside
digital environment.In a way of thinking nature inspiration, project reflects four element of nature. Those are earth, fire,
water and air.
If we are talking about nature it is impossible to skip human itself. Human is a part of nature.Those four elements common
environment is air and this takes us to Visual data. Air is common environment and touches both earth, fire and water.

Nature inspired network ideal graph

Human body is tracking by captury system and according to users movement environment is changing on video wall.

TOOLS

Captury System is used in this project in order to gather nature and human together in digital environment. Tracking people
with Captury System and then having visualization from it is achieved with Processing.After having some visual data in
Processing Video Wall is used in order to show data realtime.
While Captury is tracking people in order to create visualization inside Processing OSC protocol is used to have
communication between Captury System and Processing.

This Processing Sketch show how OSC protocol is used and how our draw function is inserted inside that protocol. First of all oscP5 and netP5 libraries are imported inside the sketch.In order to use OSC protocol we have to import those library. There are 3 messages received from Captury, they are x,y,z coordinates of the tracked person locations.
