Oscillography - Fibonacci Generator (2)


YouTube via EA78751
"Here is an excerpt from my unreleased videotape "Thirteen Meditations on the Meaning of the Tao".

The patterns are synthesized with a Lagged Fibonacci Generator (LFG) circuit built with discrete logic chips (CD4000 CMOS). The LFG is an algorithm sometimes used in cryptography to generate encryption keys. I'm exploring it as a pattern generator for algorithmic art and music. Although cryptographers like the LFG because its output is similar to white noise, I find that through creative electronic filtering, the intricate details of its cyclic patterns become visible, and we can appreciate the details."

Update via Eric in the comments: "here is a photo of the circuit in a partially complete state"

  2. Yes is very beautiful. It reminds me the Lisajous figures I did with the analog oscilloscope on my electronics classes in the univeristy. Obviously, the figures shown in this video are more complex...

  3. thank you for the comments. here is a photo of the circuit in a partially complete state:
