How can I fade from one page to another?

I want to do the following.
- Have a welcome screen
- When the user click on some of the welcome image I want to go to
another page.
- The other page should fade into view
- I also want to add some basic animation (image moving from on place
to another) while the transition between page1 and page2 occurs.

I managed to "hack" a way to do it, but I really don't like the way I
implemented it. I want to know how you guys would do it such that the
code in page 1 and page 2 stays clean.

Thanks

Phil
