Some interesting things I bookmarked on del.icio.us on October 10th, 2007:

• Mona Lisa from recycled train tickets - Employees at the Takashimaya department store in Osaka have created four reproductions of world-famous paintings using 320,000 old train tickets obtained from the nearby Nankai Namba station.

• Graffiti Archaeology - a project devoted to the study of graffiti-covered walls as they change over time. The core of the project is a timelapse collage, made of photos of graffiti taken at the same location by many different photographers over a span of several years.
• Dragonfly or Insect Spy? - Robobugs on the loose!
• Smashing Magazine Best of September 2007 - Some of the most interesting web-development-related web-sites, references, tutorials, services, tools, techniques and articles.
