We've covered a lot of tree houses, but this is the first time we've seen a treetop nest, built as a human hangout.

We also have a guerrilla sculptor of trees who's taken a UK town by storm, pics of Infiniti's new electric supercar, awesome dog sledding destinations, the most popular articles of February, and more in our roundup of the best images on TreeHugger this week.
