the Triangle game
 
a JavaScript simulation of an interesting game to play with many people.

The rules are simple:
You (in blue) are in a room with many people.
You choose two other people in the room, your 2 buddies (orange). (And for illustration purposes only, you point at them.)
Now, your job is to place yourself in the space, so that you and your buddies form a perfect triangle. A perfect triangle has all three sides of equal length.
There is two of those points, one on either side of the line between your buddies, unless that point is beyond a wall (the screen). You choose the point closer to you.
As your buddies will move around as well, forming their respective triangles, you have to adjust constantly.
For clarification: Your buddies don't know you point at them, and don't necessarily point back at you.

Click here or press Q on your keyboard to start and stop. If it gets boring, press S to add a player or press G to send the blue player somewhere.

And as you are the master, you have the following commands at your hand: (click or use your keyboard) Press M for more options.
