Hans,

Any plans for circuit diagrams? Spring-mass-pulley?

Or does something already exist that works well with Context?

What are those? stuff like the circ package for latex?

Metapost. 

Actually, what I write is often related to what I need, so as soon I
would need it, I would write something (or look at a graphic drawing
program first). It depend a bit on the needs,

Run the next mp file and take a look in GSview (nb, even fig numbers).
It need a bit cleaning up, but it's not that hard. When I find some idle
moment, I'll see if I can work it out as an example for the manual. 

input mp-tool ;

def animate (expr weight, spring, position) =
  h := spring ;
  w := h/8 ;
  pickup pencircle scaled 2.5 ;
  fill
    fullcircle scaled weight shifted (0,-.5weight)
    withcolor .7white ;
  draw
    (( 0,  0)--( 0, 20)--
     (-w, 30)--(+w, 40)--
     (-w, 50)--(+w, 60)--
     (-w, 70)--(+w, 80)--
     (-w, 90)--( 0,100)--
     ( 0,110))
    xscaled position ;
  pickup pencircle scaled 5 ;
  drawdot (0,0) ;
enddef ;

for i=.2 step .2 until 1 :
  beginfig(i*10) ;
    animate (40,100,i) ;
  endfig ;
endfor ;

end .
