These drawings were inspired by the theory of “Deterministic Chaos“.
THE THEORY: Deterministic chaos, often just called “chaos”, refers in the world of dynamics to the generation of random, unpredictable behavior from a simple, but nonlinear rule. The rule has no “noise”, randomness, or probabilities built in. Instead, through the rule’s repeated application the long-term behavior becomes quite complicated. In this sense, the unpredictability “emerges” over time.
There are a number of characteristics one observes in a deterministically chaotic system:
Long term behavior is difficult or impossible to predict: Even very accurate measurements of the current state of a chaotic system become useless indicators of where the system will be. One has to measure the system again to find out where it is. Sensitive dependence on initial conditions (a property noted by Poincare, Birkhoff, and even Turing): Starting from very close initial conditions a chaotic system very rapidly moves to different states. Broadband frequency spectrun: That is, the output from a chaotic system sounds “noisy” to the ear. Many frequencies are excited. Exponential amplification of errors: In any real world setting small amounts of external noise rapidly grow to control the sytem. If this noise is below measurement accuracy, so that an experimenter can’t see or control the noise, then the system appears unpredictable. The microscopic “heat bath” is amplified to human scales. Local instability versus global stability: In order to have amplification of small errors and noise, the behavior must be locally unstable: over short times nearby states move away from each other. But for the system to consistently produce stable behavior, over long times the set of behaviors must fall back into itself. The tension of these two properties leads to very elegantly structured chaotic attractors. LINK , WIKI
THE DRAWING MACHINE: The figures on the drawings are made by machine I constructed my slef, it uses three separate rotational movements driven by a stepper motors with worm gearbox. Two slowly spinning arms are attached with aditional 2 meter long aluminium profiles, this bonded motion makes simple 2D figures, but with the addition of the 3rd motion of turntable, it makes much more complex looking figures. Motion eg. speed and sense of rotation of each individual motor is progarammed separately and changing in time. Information about it is sent from the PC through arduino and motor-driver in to the motors. Another variables that you can change are the length of the primary arms attached to the motors, by this setting you can change the actual size of the drawing and proportion between two arms movement. Last hardware variable is the beginning angle position between the two attached arms. Just by changing this one variable you alwas get the different outcome, even if you used the same software (pre-programed figure) and other settings stayed the same.
2ZZQ Crystal Structure Analysis Of The Hev Capsid Protein, Porf2
Family: Hepeviridae, Genus: Hepevirus
These images were made form cristallographic data from PDB files. The model is representation of virus capsule made from 3D molecules locked togeather to create a holow structure for a genom. Architecture of this structure is icosahedron made from 60 units.
Hotshop “Huť František” is based in Sázava, 50km from Prague in Czech Republic.
These are vases I designed and made my self there.
This was made in CAD softaware Rhinoceros 5.0, plugin Grasshopper and Gismo.
Map topology was transformed in to lines, those divided equaly in to points, those points were prossesed by Delauny triangulation in to the surface. Then I applied map texture on this surface and set the camera DOF to highlight the most important part of the rendered image.
The coulors seen in the picture match the position and the ammount of the stress in the object. Basicaly the bigger the gradient is, there is a higher tension in the glass, that means it is more likely to break when used, beacause the stress is relaesed when the object breaks. These photos were made as a proof of concept using polarised light from a LCD screen in combination with another circular polarisation filter on the camera. As you can see, it works well.
Microwave Plasma Light
Plasma Ignition: 1] arc in the argon gas -> 2] solid sulphur melting -> 3] liquid sulphur vaporizing -> 4)sulphur gas molecules and atoms loosing electrons from orbitals = plasma = quasi neutral gas made out of positive charged nuclei ions and separated electrons from orbitals moving in electromagnetic field.
-this is low temperature plasma, only about 3000°C, still enough to melt the 3cm in diameter quartz glass bulb containing everything iside, it would melt at 1670°C if not cooled by air.
-energy is distributed without electrodes, trough the waveguide by magnetic and electric field of microwaves, 2,45GHz (same frequency as WIFI, just much more Watts)
-light distributed from this light source is made by atomic and molecular emmision, when electron from higher orbital is going on to the lower orbital, then the foton of visible light is transmited from electron
-electron gets the energy back again from the microwaves, so it is excited / jump up on higher orbital and after a while if posibble, it jumps to the lower energy level possible again while creating foton of light
-light form this source is very similar to the light made by sun, because it has continuous spectrum of clours, so you can see everything like in the day light (great for film industry or photography)
*NEW prototype HW, 1000W water cooled magnetron with cooling system for PC + variable power source 50 – 1500W. Construction of the wave guide and motor are used from the old prototype now, new design of the waveguide and motor is under construction.
Here you can see the final look of the “#Artificial_Life_Aquarell_Lighting”, based on WS2812B addressable LEDs driven by Raspberry Pi 3 + Teensy 3.2. Design of this project is made in cooperation with my friend and colleague Filip Dobias in occasion of Designblok 2016. In videos, you can see application of the generative art script, mentioned below this article. It uses cellular automata + boids algorithm to produce these beautiful fields of colors, actually it is kind of artificial life, based on simple rules developing on the 2D plane in time.
The screen is circular cutout of the matrix 30x30px = 900 px / LEDs and it has more than one meter in diameter. LED’s are projecting RGB light and mixing together on the screen made out of opal organic glass. The software is running on the Raspberry Pi 3 computer + Teensy 3.2 and it is live stream projected on the screen. The colour of the light can be off-course changed or manipulated in to the white light or any other color wirelessly from the laptop, PC , smartphone or any other device trough the VNC client.
We used this animation, as our favourite generative art script outcome. It was sourced from this amazing site: rectangleworld.com Thank you a’lot for your awesome work, we appreciate it’s simple beauty.
