Every node has its strength (represented with the size)
The thickness and visibility of nodes is determined by the strength of the connected nodes! 
The beam powers the nodes and gives them strength and goes to the least strong ones first. The shape of the nodes loops through 4 states in a 200 interval: “circle”, random positions, a spiral (not noticable on only 6 nodes), random positions on a 50px grid.
I had to reduce it to 6 nodes because of the cpu usage (more than 30%), its 15-30% now and I think thats ok :puzzle:
Post your suggestions!
