The Scope Node wireless mouse was designed by Japanese manufacturer Elecom under their philosophy of "rational design;" in this case, they were aiming to make the user feel like they're "holding a pen" rather than sliding a rock across their desk. What Elecom has done is move the ultra-sensitive laser directly under your pointer finger, rather than centering it, to make on-screen drawings more precise.

If you're lucky enough to live in Japan, you can order one here.
