That looks... amazing! I wonder how soft/firm the "pebbles" are?

I say hot...although I would be down on my knees with a vacuum every night sucking up crumbs.... very cool idea though

I like the idea, but I'd rather experience the reality in someone else's space, not my own.

Looks interesting, but how would you keep this clean?

It looks cool, but in practice I'm thinking lots of sprained and broken ankles would be in the owner's future.

I'd have to test it out. Looks interesting, unique, but it it comfortable? Does it fee strange to walk on? Will my grandmother trip and fall?

I love it. I actually am getting this... which is a smaller and probably much more affordable version for my bathroom.

Upon turning it over:

"Look honey, I found $282 in coins and eight guitar picks in here!"

I want to walk on this!
