:D yes I made it in After effects, and yes pre composing is a great tool, setting up the original "template" and then simply changing the text :)
I have finished it now, complete with sound track which I made in Logic.
I am about to upload it (which will take a few hours), so when I return from work this evening I will post a link to the new version.
I have also implemented JR's idea of using Newtons colour wheel.
thanks all for your input!
