Is there a way to opend found directories (via `find`) all in one command?

One of the things I tried to study several times and never been able to really get, is the effective use of pipe: is it maybe useful for this?

I tried things like:

```
find . -type d -name ".dir-name" | open

```

but it doesn't work. `open` is the OSX command to open a file in the associated application (Finder for directories).
