Hi, both solutions are great! This is what I had in mind, a rolling sine.
Is there a way to get the same result with the Tikz module?
\usemodule[animation]
\setupinteraction[state=start]
\starttext
\input tufte
\framed{
\startanimation[menu=yes,framerate=40]
\dorecurse{50}{\expanded
{\startframe
\startMPcode
numeric u, omega, mylength, tt ;
u := 2cm ;
omega := 4 ;
mylength := 3.141596 ;
tt := \recurselevel ;
path p ;
p := (0u,sin(omega*(mylength/100)*tt)*u) for i = 1 upto 100 :
.. (((mylength/100)*i)*u,sin(omega*(mylength/100)*(i + tt))*u)
endfor ;
draw p withpen pencircle scaled .5pt withcolor darkred ;
\stopMPcode
\stopframe}
}
\stopanimation
}
\stoptext
