[Cuis] Reconstructing Vectorised Photographic Images - ID47879.pdf

[Juan Vuletich]

Thanks Ken! It is really interesting. A friend had sent this to me just 
a couple of hours before you did.

It looks like it will finally happen. Hopefully, next year, Cuis / 
Morphic 3 will be the first desktop and ide to make it real.

Cheers,
Juan Vuletich
