The familiar high chimneystack on the TU/e Campus has been transformed by the lighting artist Har Hollands and the Honors Academy of TU/e into an illuminating beacon. LED’s have been attached to the surface of the chimneystack all around it and along its full height. Both the color and intensity of these LED’s can be controlled, making the chimneystack a tower of light, able to display and represent all kinds of things. The inspiration for the images have been provided by various groups within the TU/e, including almost every department. The start was during GLOW 2016. Now this art work will remain a permanent feature of the TU/e Campus.

Programming is made in collaboration with Rombout Frieling and jointly realized with TU/e staff and students Monique Huveneers, Diane Schoenmaker, Jérome Simons and Fenna Wit.

The fundamental cells of the nervous system are the neurons. Those cells take care of sending and receiving nerve impulses through the body by communicating through electrical and chemical signals. Those signals are pictured on the chimney by lighting the neurons and their connections, called axons.


This video is generated by predetermined dots called generators, each of these dots had a certain color. Every other point on the chimney will obtain the colour of the closest generator. Voronoi patterns can also be seen in nature, for example in cell structures or leaves. Voronoi models are also used to investigate the spreading of viruses in epidemiology.

Phase transition

In this video the phase transition of a simplified compound is visualized. When the temperature is low, the particles are in a solid crystal, wherein little motion is permitted. By increasing the temperature, the particles start to move and interact with each other more intensely. After some time, the liquid phase is reached, where particles are able to move throughout the confined space. When the temperature is increased even more, the sample will expand and form the gas phase.


Fluid dynamics is the science of understanding how fluids, or gasses, make their way through space. In this model we show how air would flow through the chimney if it was forced through it - creating disturbance, which is called turbulence. These models are also used in field as building design, aerospace engineering and sports.


A moire pattern is a special kind of interference pattern, which is created by shifting different patterns over each other. This pattern can also be seen in television screens and in printing.

Perlin noise

Perlin Noise, a gradient noise algorithm developed by Ken Perlin in 1983 in his frustration with the ‘machine-like’ look of computer graphics at the time, can often be found in CGI (Computer-generated imagery), where Perlin Noise helps making natural looking object surfaces, fire, smoke, or clouds. On the AnTUEnna, Perlin noise is used in this video to create different colorful patterns.


Displayed is a series of electrical signals of different frequencies, as monitored by a variety of laboratory equipment.

Blood vessel

The structure of a capillary vessel is visualized by means of a parallel cross section with a cylinder, showing the individual layers of cells and connecting tissue. Within the department of Biomedical Engineering (prof.dr. Carlijn Bouten and dr.dr. Patricia Dankers) synthetic alternatives for the extracellular matrix (the grey fibers) are being investigated and used in scaffolds which allow the in situ growth of new blood vessels in the body. The Animation is made in the ICMS Animationstudio.


Dancing gas discharge in an experimental microwave setup. This setup resembles industrial machines used for solar cell production. Generally, they employ very low gas pressures, but at elevated pressures we can observe these dancing discharges. In reality the discharges have sizes of a few tens of centimeters. The recordings are played about 1000x slower than reality.


As if the AnTUEnna were a real antenna, we show how invisible radio waves, which are so abundantly around us in this day and age, propagate through the sky.
