# SURFER - visitors create a maths exhibition

As part of the phaeno special exhibition “Mathe x anders“ we will show the SURFER installation in collaboration with the Mathematisches Forschungsinstitut Oberwolfach. The visitors create three-dimensional algebraic geometry in real-time - in a playful way!

Colourful forms, generated through simple formulas! The images can be printed on site and this way - step y step - a maths exhibition is created on the walls of the exhibition through the contributions by the visitors only.

We also offer you to participate from home: you can use the SURFER program to create visualizations. The program can be downloaded at www. imaginary.org/program/surfer. The pictures including the respective formula can be sent to surfer@phaeno.de. The most beautiful twenty entries are selected and will be shown in the exhibition!

The deadline for submissions is: September 11, 2013.

This user generated exhibition is part of the “phaenomenale”: http://phaenomenale.com/13/. The event is connected to the “Mathe x anders” exhibition shown at the phaeno.

## Sample picture #1

You see all points in space (in a certain range), that satisfy this equation: x^2+y^2+z^2+2*x*y*z-1 = 0. This surface is well known, it is called the Cayley Cubic.
