Scatterizationalism versus Randomizationalism In March 2015 Petra stayed for a month at the farm in Canada where architect and artist Byron Olson lives. Byron Olson is retired and has Parkinson's disease in advanced stage. Petra quickly found out that Byron Olson since long had the wish to publish a book of his work, but could not do that himself anymore. The endresult is a book designed and edited by Petra, under Byron Olson's guidance. It contains scans of more than 70 of his comical drawings and one of his brilliant stories.
