My dover edition is filled cover to cover of "60 photographic sequences". Well except for the title page and the Publisher Notes. They only tech info included in the Notes was that the grid wall consisted of grids lines marked in 5cm increments(approx. 2 inches). I don't really have a specific sequence in mind ockham. Just all in general. Yes Carolly, your right. I wan't going to sequnce them back to back. That would be far too fast motion. Many of the motions appear to have no real true way to determine a speed as some of the motions obviously involve the character having to breifly slow down befor continuing such is the case of "woman stepping up on a tressle, climbing down and turning. I suppose that for the most part all I can do is use my best guess at placement intervals. Thanks all. JanP
