How To Create The Flicker Effect?

I would like certain things on my page to show up by flickering on.

This site has TONS of flickering…

http://www.aandesigners.com/main.htm

but I just want to use the effect to present things and as an effect as thigns go off screen.

i tried doing every other frame i white, but its not fast as all. do i have to speep up the projects FPS? That’d be really fast! Looks like at LEAST 50 frames a second.

But then that would make it harder for people with lower bandwidths to view my site.

Thanks.
Daniel
