These guys did a massive floor by hand!:
A great step by step for a counter:
Tiled Penny Floor
Yup, that's right. It's a floor that's been tiled with thousands and thousands of pennies. If you're in the NY area, visit The Standard Grill to see it in person. Having done my share of tiling with mosaic, I can't even imagine. I really hope, for the sake of the back of the tilers, each penny was glued onto sheeting before it was laid. Up-close it's a conversation starter for sure, but I'm loving the texture when viewed from a bit father away. And who knew thousands of pennies could look so lux?
