We invite you to take part with your picture in the 10-day competition for the coolest surface made with the program SURFER.
Take a walk through the gallery of surfaces, transform them by changing the formula, or enter a new formula and, by rotating, zooming and changing parameters, admire the resulting surface from all perspetives and aspects.
