I do some ring magic in casual settings as I wear a bunch of jewellery all the time; 'Reflex' is great and is found here on theory11, also check out 'Divorce' by Justin Miller for another instant download. 'The Ring Thing' by Garrett Thomas is a great DVD teaching some great stuff, 'De'ring' by De'vo and more recently 'Ring Theory' by Antoine Thomas, which seems based mainly on De'vo's work! Hopefully that should get you started and give you a toolbox of stuff to start building routines!
