The instance of the electric light may prove illuminating in this connection. The electric light is pure information. It is a medium without a message, as it were, unless it is used to spell out some verbal ad or name. This fact, characteristic of all media, means that the “content” of any medium is always another medium. | |||

Visual Light Communication
( visible light between 400 and 800 THz(780–375 nm)
Light -- message
light in different frequency -- provide different function -- the “content” of any medium is always another medium?
low frequency to high frequency -- visible to invisible
- light bulb (lighting)
- lighthouse, sos light (three times short, three time long)
- Flicker/Dreamachine/(Stroboscope: initially be used to measure motors)
- detection: Optical mouse
- VLC(Visible light communication): ByteLight / Lifi (works by switching bulbs on and off within nanoseconds)
