New to AI - want examples of AI and expert systems

Hi,

I'm currently studying a BTEC Nat in Computer Science,
At the mo I'm working on AI and Expert Systems,
Part of the assignment for this requires me to provide examples of
specific real life applications of both generally AI and expert
systems.

After searching the web i found a few ideas but if anyone could point
me in the direction of some really cool commercial applications it
would be much appreciated.

Many thanks
Cheers
Bill
