May be Le Forgeron had this in his mind:
http://en.wikipedia.org/wiki/Optical_illusion
But this would only explain one part of the black-blue vs. White-Gold riddle.
Best regards,

Yes, of course. I had forgotten about that.

Thanks Jim but I think that the ??? was for "the checker board in the
shadow of a cylinder"
When I looked at the image I see gold and white with a tinge of blue.
And when I sampled the image on the BBC site the Gold was about
<125,109,73> and the other <130,136,187>, roughly.

Thanks to you and to Jim,
I think I understand the white and blue part of the riddle. But turning no color
(black) into gold (or simply into a shape of yellow)only by ligthing? That is
alchemy in a way. Johann Boettger would have liked this trick and not reinvented
porcellain again;-)
One should consider, that the hole thing may be a promotion act only. Someone
has to sell some CD out there...
Best regards,
Michael
