Reminds me of the "danger, radiation!" warning sign a local laundry put on its doors. Probably pretty effective in dissuading intruders. But, they got shut down earlier this year with a "seized by the authorities" action typically reserved for drugs/arms dealers. So, as with this copy protection label, I guess the effectiveness greatly depends on your target audience... (Side-quest: would it have been possible to mount some kind of side-channel attack against VCRs? Over-driving the video/audio signals to blow up the CRT/speakers would be an obvious one, but would this also be possibly ONLY on copies and/or copier equipment?)
