If you believe NCIS and so forth, UV makes blood and other bodily fluids 
glow bright green. (I never did figure out why...)

I've been watching Richard Hammond's Invisible Worlds. Some very cool 
stuff, but unfortunately the cool stuff is only on screen for, like, 2 
seconds, and then we get Hammond chattering some more.

I'd love to do the whole trip with time-lapse photography, high-speed 
photography, UV and thermographs, etc. In fact, I've often wondered what 
the world would look like if you would see radio waves. (I'm guessing 
that due to the absurdly long wavelength, most objects would be too 
blurry to see.) I've even wondered what the world would look like if you 
could see sound.

(Eyes and ears both detect waves. Eyes detect only three frequency 
bands, but with ludicrous spatial resolution. Ears detect waves with 
rubbish spatial resolution, but insane frequency resolution.)
