Seed Pod

I spotted this interesting seed pod in my balcony planters and decided to try and get some macro photos of it.

It looks rather like a building of some sort.

I cut it open afterwards. The interior is divided into twelve vertical wedges, each of which has a little opening at the top. Each cavity is packed with tiny seeds. Very simple structure. I'm not sure how the seeds are supposed to get out though - wind or insects maybe?
