Using acrylic as a polyffusor?

I'm thinking of using acrylic in a dual role as window cover and poly diffuser, It's and existing window which I can't move or easily block, so I thought I'd mask it with something useful while retaining the view.

Has anyone used acrylic before, or know where I might find useful information? I figure it can't be too different from the cast plastic / fibreglass sheet diffusers you can buy commercially.

That would be the cheapest way to do it; probably 3/16" sheet would do best. How large is the window, and how close to your ears? Steve

Right now it's about ten miles...

In a theoretical mixing situation (when the room is built) it'll be about 1.75m.
I know it's too close to have any real diffusive qualities as such, but the room is so small that I'll be trying to remove anything resembling a parallel surface.

What sort of negative effects might there be?

Thinking more about this. The window sill is quite high. It's about 15cm above ear height when I am sat down. I reckon if I make a curve that is like half a poly ffusor, and have it pointing slightly towards the ceiling, then it shouldn't reflect anything back in my direction.

Really this ties into the whole room layout, I'll start a thread with my plans and see what people think.
