Monome.org has announced that they are auctioning four limited edition monome 512 controllers through April 10th.
Here's what they have to say about the monome 512:
several close friends encouraged the endeavor, so we extended the proposition to a few more. ten were made in total, four of which we’re offering to the public through an auction. we don’t see a broad market for such an obtuse (yet beautiful) device but saw this as an opportunity to actually bring it into existence, if only on a microscopic scale. we do not expect to make these again. much hand wiring was involved, much wood finishing and care for detail, and in the end we’ve been reminded that we began monome as artists, not business people. so, here it is.
See the monome.org site for details.
