Via one of my favorite websites, a project that puts personal behavior data into beautifully-designed dishware: Israeli designer Iohanna Pani created mugs and plates that measure consumption using infographic illustration.
The One Month dish set shows the results of the designer's blood tests, depicted as what she calls a "cake graph" (presumably the same as a "pie chart"), while the One Week mug uses a chiseled interior to demonstrate how much coffee she consumes in a 7-day period.
The In-Formed fork has tines of four different lengths, each representing the per capita calorie consumption of a single nation (US being the longest tine and Bangladesh being the shortest).
The data visualization faucet puts water use in plain view of the user by filling a clear chamber with water is it flows from the tap. Plenty more from this collection, along with sketches demonstrating the concept and its development can be found here.
