I received this video link from Adam Horden who was at the UK Teslathon to
witness Alan Sharpes quad SSTC array audio
modulated to the Close Encounter's alien theme.  Very impressive.

Anyways, does anyone have a contact information, or website for Alan Sharpe?
I'm curious to see how he was audio
modulated the SSTC - if he was either:

1.  Using commercial PWM chip (TL494 etc...)

2.  Using external analog modulating circuit

3.  Using a PIC controller to do actual modulation

Any help appreciated.

Thanks
