Large acoustic foam blocks from Metallica documentary?

[beethovenfan]

Anyone know where to find the giant acoustic foam blocks in the Metallica Year and a Half documentary?

They were 3-4 feet high and 10 inches or so wide.

I have not been able to find these anywhere. Searching the internet does not produce anything.

Why not just use gobos?

Or you could build them:

Hard to tell exactly what those are from the pic, but it looks like these freestanding stackers:
