Judging from the wikipedia .gif, the construction is really simple. Take a point in the inner circle, and then there's a tangent line to it. This line crosses two points on the outer circle. and from either of these points, there's only one more line that's again tangent to the inner circle, and it crosses the outer circle in some point.
You add in the other tangent, and you borrow those theorems about angles on circles to show that the triangle closes.

Does this work as is or is the proof completely different?

Good luck.
