Researching Idents

To help with the planning for my ident, i decided to look at existing ones.
BBC2: Most of BBC2's Idents work around the number two. The 2 is normally the main character/object in the Ident. Something either happens to it, or it does something, like the one below. The remote-controlled 2 drives around the screen haphazardly.

Channel 4: Channel 4's recent Idents are amazing. They start of with normal seeming landscapes. But as the camera  pans around the number 4 comes together, as can be seen below. What makes it even better, it that the camera keeps panning, and the 4 is lost again.

Living: Most of Living's Idents are quite artistic. Yet they manage to link the Ident to the type of programme coming up next. I like that idea of linking it as such.

CBBC: A children's channel, i thought, would be more suited to me, as i am quite childish and crazy.Their colours are usually based around the green of the logo. Also their Idents are a mass of different places and characters containing either the B or C of CBBC. They use they letters to spell it. Educational, in a way.

So overall, i want movement in my Ident. Something on and off screen, perhaps. Artistic, yet funny or amusing. Maybe a bit of seriousness in there for my Ninja Simon. A background that does not distract the watcher from the goings on. Should my logo be a constant part of the Ident or just appear near the end?
What to do?
