_dodger, I was thinking more IR . . . that way I could project a HUGE widespread IR beam and thus rendering IR nightvision glasses useless, broadcasting widespectrum microwaves beams disabling GPS and throwing my voice to make it sound as though I'm somewhere I'm not. but that UV thing sounds ok too I guess. Of course with my luck Id get stuck in one of them baseball movies like "Buffy the Umpire Slayer" or "the Umpire Strikes Back" - TJ
