?: is an if else condition (its in the actionscript help under symbols)

if the condition before the ? is true, the value after the ? is returned, otherwise, if the condition before the ? is false, the value after the : is returned. basically it equates to:

rand equals, if Math.random() < .5, then 1 else -1;
