I've had this for less than two days now, and I've already delivered one stunning presentation with Timeline 3D incorporated into a Keynote presentation. Although the program offers *direct* output to Keynote (in HD format!), I needed to break the animation up into two parts, and exported it as a QT move that I then cut in half, then used each of these movies within Keynote. As a QT movie, you keep the ability (with your Apple Remote) to move forward along the timeline and pause/play when needed. Very Cool.

The interface couldn't be simpler. The end-product is gorgeous (you'd really have to work at it to make an unattractive timeline with this - if it's even possible).

The developer (a one-man show) is quick to respond to inquiries, and keeps a helpful blog running alongside the Bee Documents website.

Definitely give this one a try - I gambled on the $65 3D version, and I consider it money very well spent.
