HELP!

[godsreflection.livejournal.com]

I'm being forced into my sister's old room which is less than half the size of mine because I mostly live away from my home in NY (going to school in Wisconsin). Anyway, I plan on repainting the room I'm moving into and I was thinking of painting one wall (or the sloping ceiling) in a black and white (or black and another color) checkerboard. Does anyone know of an easy way to do this? I've thought of taping it off, but I wouldn't even know how to go about doing that. The walls have a rough texture to them which makes things even more difficult.
Anyone have any other funky ideas of how to paint my "new" room?
My carpeting is going to be a burgundy/wine color and the paints I have to work with are: black, white, off-white, pale yellow, bright yellow, orange, purple and maybe a teal green color.

Thanks. :c)
