I haven't tried one but I'd be interested in hearing more about it. My wife has taken an interest in forensic science lately (I hope it has nothing to do with resolving my flashaholism once and for all and not getting caught! /ubbthreads/images/graemlins/twak.gif) and I think that might be a cool gift for her. Or, er.... maybe not! /ubbthreads/images/graemlins/blush.gif
Seriously though, be careful with the UV and take it easy on the old peepers there.
