Yeah, this link is straight off /. but it's still cool. How would you
design a way of marking radioactive waste buried underground? Some very
smart people thunk it around a bit and came up with
this
(and maybe
this summary. I dunno,
there were a bunch of typos...)
Also, recently,
William McDonough
gave
a
very interesting speech on design, environmentalism, and how to not
destroy our world. I'm glad there're people who realize it's not enough
just to go hug trees, you have to show other people why hugging trees
can be such a fun
and profitable activity.
