Meta Power

I'm always fooling around with supernatural, magical type powers. I like the GURPS Magic system fine for what it is but it's rather limited and not terribly interesting. I liked GURPS Mage, but don't like the world and am not exactly happy with the system. I've also looked at Dr. Kromm's rules for Primal Powers, but want something more freeform.

Basically, what I'm looking for is something that can emulate the magic used in fiction such as Robert Jordan's Wheel of Time. Others have come up with systems, including this and this. I've got a couple of systems started, including a modification to Psionics, and I'll hopefully be posting them, soon...
