How many tiles do you need to see to recognize the image?

This is the result of a collaboration between me and Hannu Korhonen, a fellow member of the GeoGebra group on LinkedIn. He responded to my Interactive Gallery of Derivative Art with a GeoGebra applet made with GIMP. I figured out how to use GIMP, and went back a just few more years for my image. I like Hannu’s better – but I think the artist would get a kick out of mine!
