Wooten sorta treats the bass like a drumkit. Kik, snare, hihat...complete with fills and rudiments, and a whole lotta late night hours when he was younger. Plus that natural groove he just has.
You can think of your thumb as the kik, and then your fingers as snare and hats, both hands for the fingers parts; then mix it up. Amazing Grace, easy to find, is a great example of him doing this. Within a "band" context, it is simply extra percussion, adding to the drums. Wicked player, my #1 bass "hero." (sorry Jaco!)
