On the outskirts of Chiang Mai you will see something which, at first glance, looks like an alien spacecraft. Closer inspection reveals that it is a building shaped like a grand piano. So, what is it for? A concert hall? No. A music academy? No. A restaurant with a piano bar? Again, no.
It is, in fact, the Rajanagarinda Institute, Department of Mental Health. The institute specialises in the mental health problems of children. Its services include Electroencephalograms and Chromosome analysis. That's fine, but why is the building shaped like a giant grand piano? My best guess is that the architect was one of the patients.
