ATmega88 based PAL signal phasor

This is a minimalistic design of phasor device that generates PAL video signal. On screen you can see the image represented by areas of light intensity that corresponds to input voltage level. When signal level is at 0.3V it represents black area and 1.0V white. Other voltages between gives shades.

Device generates not only pseudo phasor shades but also plays music in between video signal horizontal blanking periods (sampling rate 15.625kHz). By playing totally four sound channels it gives a really nice impression.
