How to create floating ads?

Implementing floating ads that work in todays browser environment.

Came across a 'popup' floating ad on Ifilm.com first, then today on msnbc.com.

A box shows up in the middle of screen, with transparencies (i.e. the edges are irregular and you can see the web content underneath through the gaps).

Ad sits in the middle for 10 seconds, then migrates to lower right of screen in a smaller incarnation for a few more seconds, then disappears.

I need this script to promote something on my own site, where would I find one that would function in the same way without tripping pop up blockers? I for one just have the G toolbar.

I would find it hard to believe they would run such ads on such large sites without knowing that it would not set off the majority of pop up blockers? So i'm guessing there must be a somewhat safe method to accomplish this..

have you looked at the code of the pages in question ?

Javascript.. lot's and lot's of it.

I am not bright enough to rip it apart, however I can readily install a pre-made script..! :)

I have stickied the URL to you.

I don't know the page you refer to, but one technique is to have an image which loads as the last item in the html (this automatically sets the z-index). The image is given an absolute position in the html. A js script is called at page onload which rewrites the position parameters. The js script runs in a loop, incrementing the parameters every cycle of the OS. It could also rewrite the height and width parameters, or swap images, etc. If you know js the technique is actually very simple.

Sounds close to what I see, however the one I want to duplicate seems quite advanced; cookie-based, rotating, etc.

If you look at Ifilm.com, the ads should show up surfing around the main sub-pages. I can't give an exact URL as it seems to be session/unique user oriented.

Maybe there is a commercial package or a 3rd party service provide that does this? Seem's like there must be something to this effect as I've seen the system in use on several big sites..
