We wish to thank specially Jorge Royan, an artist from Buenos Aires. He is author of the painting that served as basis for our poster (which depicts Corrientes Av. and the Obelisco) and everything around widaba14. He let us freely use his painting for our conference, and we are very much thankful for that.
We invite you to see some more of his work at his web page: http://www.royan.com.ar
