I was clueless until about a month ago.
But then we were asked to design a website for Pimento Vision. They are the leaders in providing augmented reality to the commericial world in the UK.
The best way to check out their work is to visit their exhibition stand at the Gadget Show in the NEC. Alternatively you can check out their amazing new website (that *cough* we might have designed and built for them 
).
It is early days for Augmented Reality but I think it has HUGE potential for the future.
As for website design. Chesterfield is where you will find us. Away from the hustle, bustle and bloated prices.
