How can I recreate this??

nefertikaure

Hey everyone, I'm in desperate need of help. I need to know how this light/reflection phenomenon is being created: [url="http://www.yokoseyama.com/project6/project6_slides.html"] I've read the description countless times and have experimented a little bit but I can't figure it out. I do have some knowledge in spectrum but clearly not enough...I've been trying to research it but because I don't really know exactly what is happening to begin with (specific terms).

Please, if you have any ideas at all, please let me know. I'd so appreciate it.

Jess
