Telepathy Machine, Patent Number US05830064
Just saw an article on Slashdot describing a patent on a mind-reading input device, with literally no strings attached. The device relies upon the operator's consciousness collapsing quantum wave functions in detectable ways. The patent makes for interesting reading, and has references to a number of books and journal articles that look as if they may be even more interesting.

If the reports from Princeton Engineering Anomalies Research (PEAR) are actually real and reproducable, then this is all pretty amazing stuff. Humans with psionic powers (natural or engineered) is the sort of stuff I remember reading in old SciFi and Fantasy novels during high-school.
