Nanos look for each other and form groups
When Nanos form a group, the extend their
arms and create a network of lines implying
streams of information.
Press 1-5 on keypad for various grouping modes
Click to disperse nanos at any time
oh and also, this code's not optimised...at all...

Nano
Variables:
float x - x position
float y - y position
float siz - nano size
float col - nano color
float angle - used to modulate "feet"
float t - used to stretch "feet"
Methods:
void update () - nano's own motion
void display () - creates nano
