I want it in Pi because I don't own AE...yet.. I will probably get my hands on it soon though since everybody is talking so highly about it.. But even then, I wouldn't know how to use AE enough to do the effects I need..
Yes i'd like them on the screen. If possible, imagine the screen to be a thick glass and the marks would be in a glass/effect.
when I get AE i will try what you mentioned, thanks!
I also don't own AfterFX, but trace FX is somewhat I would like to avoid in PI. Since PI is merely a spite-base particle system SW. Making trace FX = generate a massive amount of particles to fill the trace area. Well, practically you don't really need that much particles but this comes another problem that: no graphic will be supposed to draw between frame and frame (non-existent frame) in PI. If you make the particle move very fast and switch on the motion blur or "Don't erase" function. There's still empty space in the motion trail because that empty space occured on "illegal" frame. It may end up that you better draw the trace animation manually in Photoshop would be more satified.
