Tim sez, "This is the pre-launch page for the Bayer 'Didget', a blood glucose meter which plugs in to the DS / DS Lite's Slot-2. Consistent glucose testing by the diabetic child (or adult, presumably) is rewarded with points in a game that can be used to buy items or unlock levels. As with the the 'iPlayer' hardware video decoder for the DS which Cory recently posted, the downside is that the new DSi doesn't have a Slot-2.
Bayer's DIDGET meter was developed in conjunction with Paul Wessel — the parent of a child with type 1 diabetes. Paul noticed that although his son Luke was constantly losing his blood glucose meter, he could always find his Nintendo Game Boy. It was this observation that inspired Paul and Bayer to work together to develop the first and only blood glucose meter that connects to the Nintendo DS and Nintendo DS Lite gaming systems to reward children for good testing habits.
