Random blink code - can someone show me how to use it?

This code comes from Claudio old post to generate random blink

tMin = 5;
tMax = 10;
function randomblips() {
        randommc = Math.floor(Math.random()*5)+1;
        t = Math.round((Math.random()*(tMax-tMin))+tMin)*1000;
        moveInt = setInterval(randomblips, t);
moveInt = setInterval(randomblips, 1000)

and this is the link : http://www.kirupa.com/forum/showthread.php?t=31891&highlight=blink

Can someone show me how to use this code?

Thank you
