try watching snowboard videos...always a good place to start for gettin some ideas.
You could always try some handplants? just ride up and basically throw a backflip except you want to plant your hand directly behind your tail (most ppl make the mistake of tryin to plant next to them rather than behind them) grab indy (or what ever you find more comfortable), spot your landing by looking back at your hand and drop back in. crucial errors people make which your gonna have to judge for yourself are speed (to slow and you wont get ya legs up, too fast and you'll either pop out or just get worked into the face.) and trying to hold it too long and then collapsing from the weight. dont know if ive explained this very well but im sure ull figure it out...thats half the fun.
EDIT: this video explains it alot better than i did
YouTube - Handplants / Inverts, Snowboard trick tip, Regular riders
or you could try a tripod

or if your comfortable enough to ride one-footed you could try fast-plants?
