Topiary

From BoardGameGeek.com:

In Topiary, players try to position their visitors on the outer edge of a beautiful topiary garden in order to give them the best view possible. Visitors can see the closest topiary sculpture to them and any behind that, in the same sight line, that are larger. You can score bonus points for visitors who see multiple topiary sculptures of the same type. Players slowly fill in the garden by adding tiles until everyone has placed all their visitors.
