[PD] acceleration - deceleration between coordinates - how to do this?

[Thomas Jeppesen]

Hi guys,

I'm working on a patch (rjdj scene) where I'm moving a little object 
around on a plane. The object is been given random coordinates which it 
is supposed to gradually move to in five seconds.

Right now my solution is to bang the x- and y-coordinates into a 
line-object which works fine, but I'd prefer for the movement to be more 
"natural". By natural I mean that the object accelerates in the 
beginning and then decellerates near the end until it comes to a full 
stop at the exact coordinates that where randomly produced..

I've been trying to get my head around a solution for quite a while now, 
but unfortunately no luck so far.

I'm sure this must be simple stuff for some of you PD-geniuses out 
there, and I'm hoping that one of you will stand up and show me how it's 
done :)

Thanks in advance,
Thomas :)
