If you’re going to be in Denver in mid October, you’ll want to take a stroll down California Street — it’s the site of this year’s Urban Forest Project, in which 24 local professional designers and 24 local design students will create banners that will hang up and down the street for two weeks. Each banner references trees (or tree-ness) in some way, and the results are sure to be eclectic.

Last year’s Urban Forest Project took over the area around Times Square in New York (you can see what those banners looked like here) and this year, the project is working to put their beliefs into practice. All the banners will be made of Ecophab, a material made from recycled plastic bottles; when the banners are taken down at the end of the event, they will be turned into messenger bags and sold by Alchemy Goods (proceeds going to charity, of course). So good work all around here. Maybe nobody’s actually planting a tree, but these designers are working to place the idea of a tree in as many heads as possible. And Denver residents and visitors will finally have something to look at besides the Rockies. Sorry, Denver.
