Hitachi Drink Coaster Print Ad

In a recent issue of Wired magazine, Hitachi has an ad with a real drink coaster insert.

You have to read the back of the coaster to discover the premise. Use the coaster as a drawing pad to design a new great invention using a Hitachi hard drive as part of it.

Does anyone remember the placemat ads for Compaq computers back in the day? Does anyone remember Compaq ™? Hint: they merged with Hewlett Packard.
