Eucalyptus trees are evil (for certain values of non-native, highly flammable, inappropriate-to-the-environment evil), but I think their bark is really pretty. There are whole groves of eucalyptus on campus. Forests of eucalyptus. Maybe they should bring in a few koalas.
This is the Singing Tree. There are three of these lead-armored 'art' trees on campus. Two of them have speakers installed; one reads poetry, the other plays music. The third, doing nothing, is known as the Silent Tree. In most places, it is not necessary to specify that a tree does not make noise.
