I'm seeing tons of comments about this thing being wasteful or impractical, as if these weren't specifically discussed in the source material. They were. They know. Here's their statement from the "Why" page:
By calling this creation an "Artistic Operating System",
we assert that it should be unique and personal, even
peculiar in its way of representing and interfacing with
the rest of the media world. In this sense, it is freed
from the implicit social requirement that new
technological projects conform to standard principles of
progress, universality and efficiency. There's no need
to claim to be the "Next Big Thing" or to even suggest
that anyone, other than the creators of this device,
should use it. However, its existence serves as a
polemic for a more diverse, inclusive and participatory
interface culture where new technological systems might
be judged for their poetic qualities instead of
marketability.
