Via Kevin Kelly’s Cool Tools email newsletter (site currently down), I read about the clever Whirl Wind [sic] Cup. It offers a tiny but useful innovation to the travel mug.
I’ll spare you the site’s Engrish and explain. As you can see, there’s a little fan installed in the inside of the cup. You press a button on the handle, and the fan stirs whatever substance you’re currently quaffing–coffee, tea, martini, whatever. Be sure to check out the nifty little Flash video on the site, which has some charming hand modelling.
