The Clever coffee dripper is a Japanese-manufactured cone brewer similar to a Melitta (but made of medical grade plastic), or the ceramic drippers (like the Beehouse, Bonmac or Hario V60) recently experiencing a resurgence in popularity. 

Unlike most dripper cones, though, the Clever marries the principles of immersion brewing—or steeping like a French Press—with the principles of extraction via pouring water over the grounds into a conical brewer which awesomely suspends the immersion until you release the coffee (via a weight-controlled valve) over a cup.
