Chroma Key Video In Action

Here's a nice trick - have a video presentation pop up on a web page suddenly whilst you are reading the page and then have a presenter talk to you.

Using Chroma Key Technology (and a transparent background layer) it is possible to do this.

Not only does the presenter appear over the web page as if by magic, it is even possible to drag the Chroma Key Video across the page, so that you can continue reading the content whilst viewing the video presentation.

It's a really neat trick, and is certainly going to have visitors to that page hang around a bit longer!
