What does the black light paper look like? If it's all dark, go out and get either a white-out pen to draw with on it, or some reflective and non-uv-reactive paint pens, that way the UV part glows, and the non-uv-reactive doesnt glow. A reverse mind-trip drawing style. :3

No, it's white sketchbook paper, but reacts really well under black light... dunno what the marker-ed parts would look like tho because I don't have a black light to test it with...

You should seriously draw Earth with a maw,

Then write the words:

"Watch the world eat itself alive"

(but that's just me.)

I say glowstick / faux poi twirling :) with someone that has also black light reflective stripes :D

Black light reactive? <=.O>

Maybe something Halloweenee , like collages of zombie furs and stuff
