Pretty cool...
That looks conspicuously like a bag I bought from my favorite surplus site,
http://www.cheaperthandirt.comyou can buy foreign bags and backpacks on there (I got a North Korean Army bag) that have dividers in them,
but look like crappo on the outside so no one wants it....I think mine was $7 or something. Might be a good base
for building this camera bag.
