Guidance Interactive have created GlucoBoy, an attachment for the Nintendo GameBoy that monitors blood sugar levels. Creator Paul Wessel noticed that his son, who was diagnosed with diabetes at age 3, carried his GameBoy everywhere. Wessel figured, hey - why not just turn the thing into a blood sugar monitor? He is also developing games that work with the GlucoBoy beyond the standard testing. Finally, GameBoys that are not only sticky with candy and soda, but bloody with glucose tests! Yummy.
