Sometimes it is hard to admit that an animation does not get better with more oscillators. Again less was more for creating a consistent illusion. This time I invested a bit more time into the fine tuning. It turned out that oscillator ratios based on prime numbers do a pretty good job.

So, what do we see? The interference of 2 8 bit noise layers controlled by 7 oscillators. That is all. Please notice, that I did not move the z parameter of the 2D noise planes.

@Mark_Kriegsman data smoothing helps a lot to make the noise look even better and more fluid. Nearly no flickering edges / pixels anymore when using bigger scale values.

The camera is focussed, the distance between the leds and the diffusor (just paper) is approximately 1cm. 251 leds @ arround 80 fps.
I invite you to take the time and watch the video until the end –

I promise you that you will see nothing twice! :slight_smile:

“Relatively prime” numbers make great oscillator values; they give the longest period between repeats.

Animation is looking great! And I see what you mean about the edges vs smoothing. Glad it helps here!

I too appreciate the noise smoothing Mark posted. Great work Stephan, I am awaiting the delivery of a spectrum shield, just so I can start experimenting with all the ‘free’ stuff you’ve posted on here.

Better you manage first to have some free days - before you start with the shield - because it is highly addictive to play with it… :wink:

Have you considered routing some variables out to potentiometer knobs? This way you could tune some of the constants or values with a tactile control - could be cool for interactivity

Yes, at home I have a fader bank for that job. Here I used a little programm as GUI which sended the parameters linked to some sliders to the Teensy. It is way faster compared to compiling it hundert times. After I found the parameters I did not need the computer anymore.
Because I basically like the external physical control and my fader bank is not really elaborate I might get myself a fancy blinky midicontroller box for sexy realtime tactile control…

Very nice - elegant solution for prototyping
For MIDI controllers, I have a launchpad mini + korg nanokontrol 2. Both were pretty inexpensive and work wonderfully. The NanoKontrol is great as a bank of knobs and buttons, I think $40
