The painting shown above is a panaroma of Rome by Stephen Wiltshire. The painter is an architectural artist who once suffered from autism. Despite of his defect, he's got a special talent of keeping a long term memory of the structure and the outline of a building. In comparison, most of us can only keep this kind of memory for no more than 10 minutes. Stephen is a genius of painting, and he has drawn panaroma of many cities including London, Paris, Rome and San Francisco.
