Heres a largely fixed version of your code, it turns out that the BIG reason
that every second vertex was zero was purely because there was no wait between
the first vertex-loop and the second.
All other changes Ive made were mostly part of my fault hunting process and can probably be reversed.
Im going to try and do a more "self-contained" and flexible version of this tonight,
but there wont be much of your code left in it Im afraid, cause I will start from scratch,
based on the webpage you sent me, rather than any of your code.
I'll post it here if I have any luck. And if my version gets posted in contributions, I'll credit you.

[Off-topic]Im in Wallsend, Newcastle, NSW myself, on the far side of Sydney from you.
So Im not really too far away, Im at work here, but I live in Morisset, a half-hour south.
