Does anyone find this worrying:

It is a very cute and cool advert for Salsa and it jumps out of your screen. For a while I have been blocking Flash in my browser just because of these take-over-your-screen adverts but that was only because they annoyed me. This advert goes a few steps past annoying to creepy. What looks like a cool effect seems to me to be a security nightmare.

For this advert to work it is effectively taking a screen capture of the current browser window and replacing it with its own interface. What is to stop a rogue Flash file taking over your browser window and spoofing your clicks to other parts of the web then extracting your passwords. Or what is to stop the script from sending a screenshot of your browser window or maybe even your whole display back to some unspecified server. The worst issue is that I have no control over whether I can let Flash to do this or not.

I prefer my web content to stay in its box. Flash is staying firmly blocked in the future.
