Wouldn't it be nice if every process could be made this explicitly easy to understand? Debayering explained with Lego, anyone?
Here's a video of something that's nothing to do with video, except that it's a type of technology.
But the way that this video makes the way a sequencer works completely obvious - to the extent that no verbal explanation is needed - is wonderful.
The tech in question is a sequencer: a device that plays notes in a pre-arranged order This happens on several parallel "tracks" and forms the basis of many modern types of music, but - stripped bare - it's fundamentally the way that Techno works.
Well done to YouTube user Optico Sonico for building this and performing in the video.
