Xbox 360/PC and Speakers question

I have one set of speakers on my desk now and one tft (Dell 2001fp with a sound bar) as I was getting fed up of the lack of space on my desk.

Now what I was wondering was is it possible to have two inputs using a splitter going into the speakers so that I don't have to swap them over each time?

I know I could get an audio switch but that seems like overkill and its another gadget on the desk I've got to find space for.

Hmmm

I tried to find something like this but I'd be buggered if I could :(

Well I went out and got a stereo twin to stereo connector and it works I can feed sound from my xbox or pc into the speakers at the same time :D
