The CDTV's Screen Saver.

This is the CDTV's screen saver, It comes on after a preset amount of time to protect the mointor.
The CDTV's screen saver bounces the word CDTV Monitors can become damaged if a single image is displayed on it for a long time so most computers have an item called a screen saver which protects the monitor.
The screen uses a 64 colour EHB (Extra Half Bright) display mode and shifts the pallet to simulate true colour (the CDTV logo is only in 63 colours but those 63 colours change colour as the logo spins) and give the wonderfull screensaver.
The screensaver delay can be set from the main preferences screen to either 1, 5, 10 or 30 minute delay or simply turned off (infinate delay, shown by a figure of eight loop.)
