Flash Player 10
I have been looking at some video tutorials about the new features in flash player 10 lately and it looks like there is some very cool stuff coming. If you look at the first few videos on the site http://www.gotoandlearn.com/ you will get an idea of how these new things are going to work. One that looks very impressive is the ability to move movie clips and images in 3D. In the video you see how simple it will be to setup movie clips in 3D space and be able to move through them with a virtual camera.
The beta of flash player 10 is already out so you can play around with it now however there has not been any update to flash yet so publishing the content is a little tricky at the moment. Hopefully there will be an update to flash soon as it looks like there is a lot of exciting stuff coming.
