Who makes large rainbow holograms?

We've got inquiry for ~2x1 (WxH) hologram to put in the window of the store, facing sunny Mediterranean city outside. Would need to be custom made.
Our reflection digital holograms at Rabbitholes would require the light from the front (i.e. outside)
I was wondering who now is still making big Rainbow holograms? Those should be the best fit, right?

I used to work in Geola and we had quite a bit of big Australian Holographics rainbows... somehow pulsed rainbows we were doing back then were not looking that clear..
I suspect that was only a matter of film used, VRP-M is quite noisy and foggy...

Thanks for the info,

Does sax3d make the Rainbow holograms with images or just diffraction gratings?
If so, can it be digital, or just mastering from real objects?

To make sure to understand you right...you need e big digital hologram of a city?
What we can do are diffraction gratings up to 1,4m x 1,02m in one pice and laminate them together for bigger ones. There we get up to almost 100% DE depending on the optical function. They are kind of digital - custom made angles of incidence and diffr. angles - but not images, not yet. But we can make them from real objects as well.
