This pic, care of the tech-blog Gizmodo, is one of a number of groovy, hot-yellow, orb-shaped bird houses that popped up on the streets of Madrid last week. Apparently, they were just a temporary addition as part of an art project that modified the yellow balls, which are usually used in construction. The exhibition begs the question: Would bird houses ever be placed on public streets as part of an urban beautification strategy? What do you think?
