I'm re-doing my room.. and i need help!?

This summer, my mom and I are re-doing my room. I'm 14 and i totally love the pink and black Zebra/cheetah print stuff. As of right now, my walls are going to be black and pink, but I want a cool way to paint them. Like my best friends sister used a "|\/|" sort of design like the first triangle was pink, then white, then black. And I want to do something cool like that. We were thinking getting a cheetah print stencil and doing something with that. But we don't know what yet. Please help! Thanks muchh:)
