Pictures say it all.
Here's the link Pete sent me - TA-05 / VDF conversion:

Here's one I found - some Japanese dude's blog. Conversion for a Max Speed Technology MS-01D. This one is nice cause it uses 2 belts - not 3 like the TA-05 / VDF conversion:

Conversion for Street Jam OTA-R31:

If you find more of these conversions please post them here. I'm hoping someone in NZ will get one of these (or even better, make one) cause I reckon these are super cool.
Cheers,
Richard
