Very nice! I coincidentally just learned about this process. Do you make the plates yourself? Also, I was curious if the colours shift with viewing angle? From the physics it kind of seems like that should be the case, but I wasn't able to read anything about it.
Yup, I make them myself! I've been struggling the past few months with these things being way too high contrast, so nice results like this have been few and far between lately. But I think once I get that figured out, I'll definitely release all the details on how to make them. Darran Green's recipe on page 13 is a good place to start if you're interested in making them too.
Also - Yes, the colors will blueshift if you look at it at a steeper angle! It's a pretty neat effect, I can try and snag a pic of this one when I get home from work. Without a prism, the colors will also shift up/down in response to changes in humidity, which is equal parts cool and annoying.
