Strapya has an extensive collection of charms to attach to your ketai including one called Revolve Game which has pinball, space hockey and car racing (to name a few) all packed into a 55mm x 40mm micro package. The unit runs on two LR44 batteries and has an auto power-off function that shuts down when idle for 3 or 4 minutes. It comes in 10 colors and has 99 levels of play – on the black & white screen – for only 680jpy.

For those with slightly more expensive tastes, also see the solid gold 30,000jpy wild boar strap. Via the always interesting Tokyo Mango.
