Ok this must be the most most esoteric and difficult to find amiga hardware ever 
Very Vidvid Mandala software was a VR program for the amiga.
I have a dongle to sell. That will authorise a copy of the software to run. That software has never been cracked, as it was very rare.
You need to have the software and a Live board to use this fully.
I had a setup back in the day.
It was a lot of fun and kinda of complex.
the amiga with all it's stuff, the live board, the camera, audio, we used midi too.
You can PM me with what you want for this "dongle" (will want to see pics) verify it's still good.
