It's a mouse, it's a television remote control -- really, besides a bag of chips and a great Belgian lager like Budweiser, what else is needed for a sedentary lifestyle? The C@T-one (get it, cat one?) ships with a 2.4GHz wireless USB dongle and should work with your PC-based media center or FORIS.HD TV. ¥12,600 (about $120), problem solved.
Update: This little remote works with a wide variety of televisions, tuners, and video recorders from Sharp, Sony, Panasonic and many more. Full list after the break with a picture of the device in hand for scale.
