PLEN (the most over-priced best desktop gadget of all time) is now being offered over at Audiocubes in a limited batch of 50 for $3,000 USD. With Systec Akazawa gone bust in January 2009, these might be some of the last PLENs available. And now you can download apps for your iPhone or Android phone that make controlling him a breeze, though perhaps not quite as fun as the more tactile Walky app developed by Yuta Sugiura. The dance mode looks especially fun. Videos tucked after the break.
