Libyan Desert Glass is strewn over an area of hundreds of square kilometers in the Great Sand Sea, a region desolate even by the high standards of the Sahara. As one account of a recent trip to acquire Libyan Desert Glass puts it: "Out there, death sits on your shoulder like a vulture." While some would have you believe that Libyan Desert Glass is evidence of ancient atomic warfare, it is probably evidence of a massive meteorite or comet explosion nearly thirty million years ago, similar to Tunguska, but much bigger. The stone age Aterian peoples made tools from it, but the remoteness and inhospitality of the Great Sand Sea has ensured that until recent times it has mostly been undisturbed. However, a breast ornament buried in Tutankhamen's tomb has a scarab made from Libyan Desert Glass, the only piece made of the material to have been found by Egyptologists, and how Tutankhamen's jewelers acquired it has remained a mystery. Until now. [Previously]
Markus Kayser has designed and built The Solar Sinter, a solar powered 3D printer which creates glass objects out sand. Needless to say, the ability to create objects out of sand using solar power will be welcome in deserts. He took his machine into the Sahara desert to test it. Previously in the Sahara Kayser tested a similiar machine, The Sun Cutter, which uses a ball lens to create a kind of laser cutter.
Sahel Sounds is the blog of ethnomusicologist Christopher Kirkley, a.k.a. MeFi's own iamck. It's about the contemporary music of the Sahel, which is the Southern border of the Sahara, focusing on West Africa. It has long been a region of great musical ferment. The most famous musicians today are Tinariwen (previously), but there's a great deal more out there. Kirkley travels around trading music, Western songs in exchange for Saharan, which he mostly receives off cellphone memory cards. Kirkley has made three compilations, Sahelsounds, the Promo CD and Music from Saharan Cellphones volumes 1 and 2 (the numbers link to downloads). Kirkley has also collected and recorded videos. The Guardian interviewed Kirkley on the subject of cellphones' effect on Saharan music, which he has written about. Mark Richardson of Pitchfork was prompted by one of Kirkley's collections to write about musical scarcity in today's infoglut society. Besides the collections, there are a lot of other songs on the blog, the entire archive is wonderful and worth reading through.
