You might find it more in commercial buildings like airports and schools. We once owned a 1920s home with terrazzo floors in the bathroom. That started my infatuation.
I know it is an expensive process to create an entire floor but if I can capture a little bit of the look with a couple planters? My eyes would be happy.
Because of the weight I would keep my eyes open in local garden stores so you are not paying for shipping. If there is nothing near you www.netshops.com is selling a version on sale for $60 (2 for $105). These would make great table toppers with some spiky purple grass or green moss.
