Emanuel Dimas de Melo Pimenta started working on architecture and urban planning in the early 1980s. Then, he coined the concept of "virtual architecture" and launched Woiksed - the first virtual planet of the world, anticipating Second Life in about twenty years. From a floating island to a building created after mathematical principles -each one of his architectural designs is an exercise of discovery and invention. The book 30 Years of Architecture shows sixty of his works, created between 1980 and 2011.
