Scanning disk television

[yagosaga]

Before some weeks I got a scanning disk from Peter Yanczer. This weekend I have assembled a very simple scanning disk televisor with the first results, see

Is somebody here who experimented with mechanical television? The televisor now is without motor synchronisation. Two MPEG videos demonstrate the effects.
I can install an automatic synchronisation or a manual remote control for the motor similar to that of early scanning disk tvs. What will be a better way?
