1. A summary of the progression made on REFLUX 2.0 during the first one and a half SDL week. A lot of problems as well as opportunities were discovered and the final form of the second prototype is almost worked out.

     
     
  2. We divided the feedback from the experience test into three categories:

    - The experience of walking by Reflux 

    - Comments on the installation specifically

    - Possible future applications

     
  3. At the exhibition we received a lot of useful feedback to our prototype, eventhough the interaction with people was not working yet. Afterwards, we were determined to an experience test with a completely working prototype. 

    We told people to walk past the installation in any way they wanted, individually at first but later in groups. The results were even more interesting than we thought. 

     
     
  4. A video full of people streams, chaotic and understandable.

     
     
  5. After looking at various ways of projecting the light, we chose a big light source to get an out-of focus image. This made the projection look more like a light substance and it showed the movement of the waves better. 

     
     
  6. A sneak peak of our exhibition stand, we are satisfied! The movies of our road to this prototype will be online soon.

     
  7. Having had some serious water damage due to a leak in TU/e’s main building, we rescued almost all our stuff and finished the construction of the final prototype.

     
     
  8. In this movie we try to control electro magnets with an Arduino. In the ideal case, we can control the magnets with both positive and negative power with difference in intensity and smooth transitions.

    We used PWM (pulse width modulation) to get a variable voltage on the electromagnets and we looped it in a certain rhythm to test it. It worked! Now we still need to map it to the sound input.

     
     
  9. This is the plan! We will visualize the movement of people in a projection of light and it will follow this path:

    PEOPLE in a public space make

    SOUND is digitally mapped (Arduino + electro magnets) to changes in

    MAGNETIC FLUX causes movement of the buoys in

    WAVES create differences in the direction of the

    REFLECTION of light on a projection screen/ceiling/wall

     
  10. Before we could start building our final prototype (BUOYS 3.0), we had to determine certain variables. We wanted the movement to be controlled, understandable, relatively slow and intriguing. In this movie, the weight of the individual buoys, the suspension point and the distance between the buoys are explored.

    Apart from those variables we explored the friction in the suspension, the length of the buoys and the magnetic force of the magnets. This way we ended up with a set of variables for an ideal movement, in our eyes. Building can start!

     
     
  11. After exploring the moiré and the magnet mechanisms, we concluded that the movement of both was very interesting and beautiful. However, the moiré technique didn’t really fit our concept of visualizing complex movements by translating them into geometrical patterns. We decided to stick with the concept and continue with the Floating Buoys. 

    After the first experiment, we tried to make a grid with the buoys instead of just a single row. The movement of the waves in the two different dimensions was something we were curious about. In the end we built a surface that has many of the same qualities as a water surface and we already started to experiment with the light projections a bit. 

    The biggest part we still have to do on the movement is the initiation. We thought of using electromagnets to silently initiate waves from every angle and starting point while having great freedom in intensity, frequency and direction.

     

     
     
  12. As a kickstart for experimenting with moiré, we ordered the book ‘Magic Moving Images’ which featured various kinds of moiré effects. When we started experimenting ourselves we found out that when using moiré with simple moving patterns instead of frame-based animations like in the book, the movement and shapes became more natural and surprising.

    It became even more interesting and very water-like when we used semi-transparent patterns. This was mostly done digitally, and sometimes we used Processing. Another interesting addition to the effect was the bending of the lines, which created a wave-like movement.

    Until now, we didn’t succeed in the creation of geometrical patterns from complex chaotic-looking movements but the effects we discovered were, nevertheless, very beautiful and intriguing.

     
     
  13. After the Theme Days and three weeks of Self-directed learning, we decided to work out one concept: the ‘water reflection’ one. Our coach gave us the advice not to use real water for this, because that would only make it harder to grab the essence of it.

    We took this approach and did a first step in recreating the essence of water movement. After a brainstorm, we came to amongst others Moiré and magnetism as phenomena to experiment with.

     
     
  14. Our two concepts for the Theme Days: 

    Suicidal/resurrecting: The matchsticks move towards the fire, which kills them in the end. The movement of the matchsticks has some very characteristic qualities and metaphorically it can be used to visualize bad temptations like going to bed late or eating unhealthy food.

    Water projection: We want to capture the origin of very complex movements (like water waving) using light to get a simplified image of this movement. 

     
     
  15. After ensuring ourselves that we explored all possibilities well, we decided to work out the water reflection concept some better because we were going to present it at the Theme Days, which are a good opportunity for feedback on our two concepts.

    We wanted to get better control over the movement of the water and its derivative, and therefore we made a system with a manually controllable water pump. It worked pretty well, we got variable geometrical patterns as an image, but it was still a very literal translation of water movements.
