I found this via MedGadget: Glucoboy -the first blood glucose meter that has been designed specially for kids, adolescents and the young at heart.

he Glucoboy is an advanced blood glucose meter that is extremely accurate and highly precise using only a 0.6µL sample of blood!

When used with the Nintendo Game Boy® Advance System or the GRiP incentive-based web community, Glucoboy becomes part of an entire network that rewards testing compliance and good health management.

Glucoboy is much more than just a meter, it is an integrated system that assists patients and support networks, helping them work together to provide the highest level of care, compassion and compliance.
