I collaborate with Flourish Klink on two very specific Tumblr blogs, which are both open for submissons.
streetcrts.tumblr.com features photos of CRT televisions (or monitors) that have been placed on the street to allow others to take them away, or to allow them to be removed as trash.
xavierpauchard.tumblr.com chronicles, in photos, the legacy of industrial/furniture designer Xavier Pauchard, who, without formal training, designed steel furniture early in the 20th century that seems to be in about 1/5 of all New York restaurants, bars, and coffeehouses, and in many, many other places worldwide. Pauchard does not, as of this writing, even have an English-language Wikipedia entry.
If you spot street CRTs, or the furniture of Pauchard, please submit photos to these two sites.
