was thinking more about this and it may be possible to make a contacts app that has a mini gallery slide show with speed options.. really i would like something like this integrated into the default contacts.apk!!
So basically what you want is a video or slide show to pop up when people call? Sounds like something that maybe the CM team or a dev with a lot of java knowledge could do, if it can be done.
I'd be happy w/ a full screen caller ID...
