I haven't used the animation nodes addon in a while - so I dug it up and created a new animation with it. It took me a while to get it running on my box due to python installation absurdities but I finally got an 1.6 up and running in my blender 2.78 installation. For this animation I used an empty list of vectors and filled it with random vectors generated by a vector-wiggle-node. I then used these vectors to create curves. Since I wanted to create a knot I used a second loop that creates several of these splines and adds them into a spline list. This spline-list is then added to a new object and rendered.

I saw a hudini video tutorial a few weeks ago that shows how to use a noise field to create particle trails that look like electronic schematics. I really liked the effect and recreated it using a small processing script. To create the effect I set up some particles, that use a noisefield to influence their velocity. Before the velocity is added to the particles potion the vector is normalized and then each component is converted to an integer value - this limits the values to the x and y component to -1,0 and 1. The resulting vector is then scaled to the original length of the vector and added to the position of the particles.

For this animation I created a particle simulation with fluid particles emitted from an icosphere. The particles are emitted along the y-axis and hit a forcefield, with the flow parameter set to 0.1. I used the cubesurfer addon by pytoevil to create a mesh from the particles.

I used the blender explode modifier to move the vertices of an icosphere in a turbulence forcefield in blender. The particles that move the vertices are form the same icosphere that acts as the emitter of the particles. If you do that make sure the particle system is the first modifier in the stack and that "use modifier stack" in the particle settings is NOT ticked. Otherwise this leads to pretty wired behaviour and probably a blender crash.

The forcefield has an increased flow parameter as with all my flow experiments.

To make the shards look like 3D objects instead of thin paperlike triangles I used the solidify modifier to give them a little bit of depth.

For this animation I combined a vortex forcefield and a turbulence force field. As with all my latest particle experiments I increased the flow parameter of the turbulence forcefield. The particles are emitted by the faces of an icosphere.

For this experiment I used the turbulence forcefield with the flow parameter set to 2.0 to influence a set of particles using an emission shader to make them glow. I also used the "Mesh from Particles" template of the animation node addon to create the network.

In the compositor I used a defocus node to create the depth of field effect and a very slight lens distortion to add the dispersion color distortion at the edges of the image.

I created another particle set that interacts with a turbulence force field with the flow parameter set. This time I used the bTrace addon to trace 500 particles and create the purple particle trails. The bTrace addon creates the curves by stepping through all frames, taking the particle position and adding a new vertex to the curve.

I copied the purple material to all curves by selecting them and selecting Ctrl-L and "Material"

For this animation I used a turbulence forcefield to influence a set of particles emitted by a plane. at the beginning of the animation the flow parameter of the forcefield is set to zero. I keyframed the flow parameter and increased it during the animation. In the end the flow parameter stays at 1 to prevent the particles from leaving.

I created another particle simulation in blender - the particles are influenced by a turbulence force field. The size parameter is set to 2 and I increased the flow to 1. When this parameter is set the particles start to rotate and behave like in an air current. The particles are emitted from an icosphere with subdivision level 2 and flat shading.

another particle animation in blender - I created some particles that take off from a plane and drift off the screen at a random speed.

I added a fresnel input to blend between the diffuse- and the glossy-shader on the sphere material used by the particles and I lit the whole scene using a sun light to create the shadows on the floor plane.
