I am joining others in not caring about the legitimacy of Elecom's claims of precision based on positioning the laser between your thumb and forefinger for their Scope Node mouse. This thing looks awesome.
Joel @ BBG is right on saying that the Scope Node is "designed with the clinical asymmetry that the Japanese do so well." It looks like at any moment, one of these panels could swing out, revealing even more intricate robot innards. It's around $60 in yen, with no obvious plans for a US release.
