the VTC video course, whilst expensive is *DAMNED* good and got me up to speed with AI in a morning... I'd bought a book before but taking text to mouse wasnt that hot... Learning the curve drawing is the tough part, everything else is a doddle.. However - a book i *excellent* to leaf thru (get one from the library) as you can quickly see all the useful tools there are in there!
Best of luck - perservence is the key - and dont tackle something huge first!
