Wow! Such a great art idea! I live in a small town in south of Brazil, here we have some of this silos, mostly for grains, like corn, soy, beans. But, something in the cultural patterns of people here cannot make this possible. Unfortunately "street art" or variations have minimum space here, its just not natural, maybe cause the culture of the traditional families, dont know. But, love to see this art! Thanks!
It's odd that your people there would rather see a plain white silo instead of a magnificent piece of artwork. Hmm...I guess like you say, it's probably cultural. Thanks for commenting though, I really appreciate it.
