Martin showed me a cute little random walk script for the demo at
http://js.io/#worlddemo. Thought I would share it :)
javascript:jsio('from examples.world.world.constants import *');
(function(f){setInterval(f,5000);f();})(function(){client.move
(kBounds.maxX*Math.random(),kBounds.maxY*Math.random())});void(0);
