Oscilloscope display of a Fibonacci Generator

Craft & Design Technology

Once again, Eric demonstrates the intricately beautiful results of mathematics/electronics –

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.

A near complete version of the circuit used is available for viewing here. [via Matrixsynth]
