Here are a few contributions that I made myself. I'll be posting more as I do them, primarily to give people ideas. The first one is a 2.5 cm square wood sculpture (wood burning is a major source of PM), then a 2.5 cm diameter ball of steel wool and twine (represents industry). The next two pieces are 2.5 cm square and 10 cm square laminated actual PM10 samples taken from Sacramento, CA (smaller one) and Calexico (larger one).
Eric, thanks for the awesome picture of fluorescent brain cells. Cellular biology rocks!
Great picture, thanks. I also really enjoyed the enclosed literature.
Wonderful 10cm and 2.5cm works. Cool idea for a way to send them too. Thanks very much Chantal!
Roberto, I do know of Sao Paulo. I hear it is one of the largest cities in the world. Particulate matter levels tend to be higher in the winter everywhere. The cold, still air, low inversion layer, and people using their fireplaces makes Winter the 'high PM season'. How is the air there in Sao Paulo typically speaking?
A couple wonderful 10cm postcards from Germany. Very topical, and bonus points for incorporating a dinosaur.
A contribution in the form of the famous and long-running 'Brain Cell' project from Ryosuke Cohen. Thanks.
Wow! What an amazing contribution Vittore. He sent in the 2.5 cm piece, 10 cm piece, and very impressive mini rubbertamp all shown here along with much, much more. Thanks!
Thanks for the contribution, Lubomyr, and kudos on the use of recycled materials.
Another contribution from Helene Lagache of France. The text translates to "A Little Air on Earth". Merci.
This piece of mail art titled "Touch by Man" was received in a clear glassine envelope. Thanks, Jonge.
