Design studio Transparent House has a neat new way of dressing up stark industrial bare concrete floors. Supposedly their floral patterns can be applied to both newly poured floor and that where the concrete is already set.

No details on their website, so I'm guessing it's some sort of a sandblasting or acid-etching technique. Link [Flash, click on Portfolio, then Industrial Design if you don't see it at first] - via RuebenMiller
