Any BTTF giant speaker attempts?

So... Anyone try it yet? Looks like someone can use foam noodles (pool toys) for the blue outlining, foam sheets for the main grey sections,looks easy but maybe have to be in a garage or outside for display...

these should be pretty cheap and found at wal mart, toys r us, etc.

I seen some big prop speakers in music videos that used salad bowls for the center silver part

Mythbusters did build a speaker about that size...maybe a little smaller.

Measuring by MJF, I'd say its like 5 n a half ft diameter maybe a 7x7 box, my rough estimates though
