+== Braiding ==
+<br>
+This "braiding board" is an experimenting platform for different braiding techniques.<br>
+Its level of complexity can be modified by changing different parameters. <br>
+It consists of five "thread ports"and "thread gaps", forty interchangeable "spacers"and fifty "spacer slots". <br>
+<br><br>
+Components:
+- Wood (left over) <br>
+- five pieces of thread <br>
+- forty wooden dowels <br>
+- and five screwable rings <br><br>
+[[File:thread_cont_board.jpg]]<br><br>
+How to use it:<br><br>
+. Define your setting: plug the spacers in / out <br>
+. Insert each thread into a ring <br>
+. Think of an algorithm / a braiding technique / your experiment <br>
+. Note: the order of the threads in the "clipboard" (bottom of the board) makes a big difference <br>
+. Start braiding! <br><br>
+Some first experiments:<br>

+Complexity + knots by following the "clipboard" order and a simple algorithm: left, right, ...<br>

+== Networks ==
+<br>
+How can we visualize or encode networks in a different way than we are used to ?<br><br>
+This sketch is a proposal to transform networks and their different parameters by shaping braids / thread patterns. <br>
+It is not predictable that random braid configurations evolve into proper braid structures that can exist without any outer support.<br>
+Therefore the "machine" above ("braiding") shall be used to set up a thread-path that does not fall apart easily.<br><br>
+The structure of the transformation is defined by several parameters that represent different properties of the network.<br><br>
+Example:<br>
+- the network could visualize trading routes between cities<br>
+- the colors could then represent different goods, for instance: yellow = red pedal boats<br>
+- A,B,C and D represent the nodes of the network. In this case they could represent the cities.<br>
+- the amount of goods can be represented by the location of a color inside the four squares of A,B,.. counted from left to right.<br> If the second square of A is yellow than this could mean that city A has 200 paddle boats.<br>
+- now, a match of the colors AND the locations of the colors inside of A,B,C or D means that those two or more cities (nodes) exchange goods (are connected).<br>
+In this example: A and B's second squares are yellow -> those two cities trade 200 paddle boats.<br>
+- if there is no match then there is no connection.<br><br>
+The "braids" and the network drawings can be infinitely translated into each other.<br><br>

+== Levers and Cranes ==
+<br>
+How can we move something in every three dimensional direction? <br><br>
+A mechanical feature of thread is that it can pull - but it can't push. <br>
+This structure helps to move things with thread by the use of additional mechanical support.<br>
+It is meant to be used by two peoples who operate two strings (yellow, each person) in order to move the object.<br><br>
+One important part of that structure is a spring (green). <br>
+It is attached to a fixed spot in the room. It stretches and contracts itself when the attached object is moved 1) parallel to the ground and 2) up and down. <br><br>
+Another essential aspect is the thread that goes through / is attached to the middle of the object. <br>
+It holds the object in place so that a precise movement is assured.<br>
+It also takes away some of the objects weight in order to exonerate the operator strings.<br><br>
+A third important part are the structures that attach the "middle-thread" (red) to the ceiling and the ground.<br>
+They 1) hold the middle-thread in place, they 2) react to the operators movements by turning in the required direction (blue wheel) and they 3) provide a bracket for the spring.<br>

+== Pulleys ==
+<br>
+This is an assembly kit that allows to work with pulley/thread constructions in a flexible way. <br>
+It works best with flat and smooth surfaces and it can be used in vertical and horizontal constructions<br> (such as logical operations, see Rachel Smith's and + or gates).<br>
+The parts:<br>
+) 3D printed pulley wheels <br>
+) metal ball bearings <br>
+) plastic suction pads and <br>
+) thread.
