Shoshanna: Sounds like you and VituallyHistorical should get together and compare notes and/or reference material :) I don't know if Cinema 4d has the functions - but I think I recall a tutorial somewhere that uses those particle emitter type things to spray particles in a whirpool/funnel type pattern then replacing each 'spot' with an actual object - that might work to make a mail twister... Hopefully one of the Cinema 4d users about here will be able to shed a little more light on that option..
