VHDL gray code counter

Question

I'm trying to implement a gray code counter using a shift register and a 4-1 MUX. Does anyone have an idea what logic to use?!

Thanks

I'm having a hard time not adding the snarky answer of "boolean". Can you describe your approach and how it's failing? — em.eh.kay, Jan 14 '13 at 19:43

I am not sure if this satisfies your requirement of "using a shift register and a 4-1 MUX", but here is a small and functional gray counter reference design by Altera:
