Ken Saro-Wiwa Foundation. Note in the Board Members section that it offers a glimpse into what Ken Wiwa is doing now.

Here's a recent interview from Democracy Now, also featuring Kenyan Nobel winner Wangari Maathai.
His Toronto Globe and Mail page (even is you don't venture past the registration wall) gives you a sense of his current concerns.
