Butterfly effect. This took ages to do. I didn´t even count hours, and the guy who scans images here at the news desk propably hates me by now. The idea was to create a "school table" with ten butterflies you can easily see in your own garden in Southern Finland. A butterfly expert at the University of Helsinki helped me pick the spieces, and then I checked in books and different internet resources and started painting. My favourite is Autographa Gamma (botton right corner), so simple and beautiful.
