The Body Check Ball from Japantrendshop basically “lets you get an accurate, detailed picture of your health, anytime, anywhere — has sensors to read your body fat, bone density, and muscle percentages, and displays them all on an easy-to-read LCD screen.” Product page.

The ball supports up to 10 different user profiles, and I assume it will keep track of past measurements for comparison. It also doubles as an alarm clock.
