Attached Link: Towards Walk Paths for Props

One way to make a prop follow a parabolic curve is to use a Walk Path and the Walker3D figure. See the link above for details. Another way is to use one of VK's figures, from this URL: http://www.renderosity.com/messages.ez?ForumID=12351&Form.ShowMessage=2327074 Ockham made a Python script that could also do the job, but I don't have a link for it.
