Are there any good examples of this anywhere? I've been trying my hand at it, and it's... decent, but I can't get it to look quite right. Some kind of tutorial from a master animator would be a miracle right about now. <img src="smileys/smiley5.gif" border="0" align="middle" />

For smooth flashing:

Once per second:

Set Opacity: 50*sin(time*360)+50

Twice per second:

Set Opacity: 50*sin(time*360*2)+50

Or for a traditional flash (visible/invisible):

Set Opacity: 100*(sin(time*360*2)>0)
