An interesting delay effect I've used:
W --->| | ---> | Delay1 | --->| | ---> W' X ---> | B-format | ---> | Delay2 |--->| A-format | ---> X' Y ---> | to | ---> | Delay3 |---> | to | ---> Y' Z ---> | A-format | ---> | Delay4 |---> | B-format | ---> Z' Delays 1-N are separate delay lengths. The B to A-format conversion splits the input soundfield into four separate sectors. (I think of them as slices of pie!) The resulting delay splits the soundfield up--so that different parts are delayed differently. I usually throw in a rotation (...tilt, tumble...) or two to liven things up. Easy to do w/ Csound, MaxMSP, Pd, SuperCollider, Bidule, etc....

That's very similar, in fact, to the field delay function Dylan had in his LAmb software for the SGI Indy computer, back in 1996...
