Ended up with,

PHP Code:

function onCreated()
{
  this.amp = 0.2;
  this.period = 4;
  this.initialy = 2;
  setTimer(0.05);
}

function onTimeout()
{
  this.value += 0.05;
  temp.value = (this.amp*sin((this.value*this.period)+this.initialy));
  setTimer(0.05);
} 


Created a nice little bob =)

End result is on Litheria above a sign =D
