  The Top New Videos list is always full of interesting, current videos. It is always recommended that you have a look through the Top New Videos, but also have a look at these:
  - Upcoming Unsifted Videos - active video submissions that neither are published to the front page nor archived to the submitter's personal queue
- Have you seen a really funny, surprising, scary, interesting, cute or in any other way extra good quality video?
  Post and share it here - VideoSift is the best video aggregator on the Web, where we share, discuss, promote, and interact with the best videos out there on the web. Post it here, and share it with the large community of video-interested users. And - you are guaranteed to find more very good videos here already!
  Mind you, we only share videos you discover that someone else has made; if you "self link," by posting a video you have made, have posted or have interests in, you risk the ban hammer - read the posting guidelines before posting. The sift is NOT for promoting your own videos - it is for sharing videos others have made.

Oscillography - Fibonacci Generator

submitted by Stingray

1 decade 5 years 10 months ago

From YT desc:

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.

Digital patterns from the LFG are converted to two analog outputs with separate hardware of my design. These analog waveforms were processed through an Electrix Filter Queen resonant filter, and visualized on a high resolution Tektronix X-Y monitor. The video was recorded to VHS with a camera pointed at the screen. The audio was recorded directly, and contains the same waveforms being displayed. Although youtube doesn't allow you to hear it in stereo, the left channel corresponds to vertical motion, and the right channel corresponds to horizontal motion.

What you see is what you hear, in other words.
