Dune Ash
Dune Ash is an interactive simulation of a volcano eruption in Europe. You can place a volcano, add a wind field and explore the ash cloud dispersing in time.

The Lorenz attractor
Submitted by Aurélien Alvarez on
“Predictability: can the beating of butterfly’s wings in Brazil cause a tornado in Texas?”
In 1963, Edward Lorenz (1917–2008), who was very interested by the problem of convection in the Earth’s atmosphere, drastically simplified the NavierStokes equations of fluid mechanics, well-known for their intricate complexity.
Dimensions
Submitted by IMAGINARY on
Nine chapters, two hours of maths, that take you gradually up to the fourth dimension. Mathematical vertigo guaranteed!
Berlin Subways – Periodic Timetable Optimization
Submitted by Rolf Möhring on
The Berlin Underground features nine lines that meet in 19 transfer stations. How to compute a periodic timetable that minimizes the total waiting time of all the passengers in this network, while respecting all safety matters? This is a highly complex task that has traditionally been handled manually by splitting it into subtasks.
LPDJLQH D VHFUHW

An artistic journey into the world of elliptic curve cryptography.
Sliced IMAGINARY
Submitted by IMAGINARY on
The sliced IMAGINARY exhibit should be printed on two different colored thick cardboards. Cut out the pieces and don’t forget the slices. Plug the pieces into each other. Note that the different colors are orthogonal to each other.
Twelve Algebraic Sculptures
Submitted by IMAGINARY on
For the exhibition “IMAGINARY - through the eyes of mathematics” we printed twelve algebraic surfaces as 3d-sculptures using additive manufacturing techniques. Since the surfaces were only available in an implicit way (as the zero set of an algebraic equation), we first had to produce the necessary explicit 3d-data (triangle mesh). Please find here the resulting stl-data. We hope you find it useful to produce the sculptures with your (or any) 3d-printer. However, some modifications are likely to be necessary. They are mentioned and partially linked to in this text.
Herwig Hauser Classic
Submitted by Herwig Hauser on
Herwig Hauser’s classic algebraic surfaces are compiled for the original IMAGINARY exhibition. Herwig Hauser’s forms and formulas are chosen in such a way that equations are simple and beautiful. The figures are plain and natural and show interesting geometrical facts. Herwig Hauser is professor of mathematics at the University of Vienna and works in algebraic geometry and singularity theory.
Oliver Labs
Submitted by Oliver Labs on
Oliver Labs is a geometer specialized in algorithmical aspects. This includes the construction of interesting curves and surfaces, their visualization and the study of any appearing algorithmic problems. These pictures are algebraic surfaces with (amazingly) many singularities.
Crystal Flight
Experience this interactive program and fly through a quartz, fluorite, or diamond crystal. You can steer a miniature spaceship through the crystal structures using your finger on a touchscreen, also in 3D.
