hologram effect

[marcros]

What is the term for that hologram effect that you get on some timbers as it catches the light- for example quarter sawn london plane, sycamore etc. Its name escapes me and somebody did an article about it- without the term I cannot search Google!

begins with a C if that helps...

Cathedral?

Close Grain

Flatsawn (bark side up) vs. quartersawn (bark side left). The cathedrals in the face of the pine are replaced by nearly straight lines in the face of the oak. The pale streaks in the oak are the ray flake. As you move your head around to change the viewing angle, the light makes them shimmer like some 3D holographic effect.
