*'''Keep''' and mark as stub. Maybe someone will expand it one day. --[[User:Gabi S.|Gabi S.]] 17:29, 24 June 2006 (UTC)
*'''Delete'''. It's just three graphs. Limited context, this is a dicdef at best. [[User:Ifnord|Ifnord]] 19:11, 24 June 2006 (UTC)
*'''Comment'''. The article does not make any sense to me. What is this "motion" thing? These curves are not wiggly worms, are they, that change shape as you look at them? What is on the horizontal axis of these curves? Isn't that time? So are there two kinds of time, a meta time for seeing how evolution in normal time evolves? And on whose authority does Wikipedia claim that shift, rotation and curvature are the three main movements? Rotation looks like pseudo scientific junk; it does not commute with linear scale transformations and can turn graphs of functions into non-functional graphs. "Curvature" does not appear to mean what [[curvature]] is supposed to mean. --[[User:Lambiam|Lambiam]][[User talk:Lambiam|<small><sup>Talk</sup></small>]] 19:18, 24 June 2006 (UTC)
