"The hardware to be used was a Prime 300 connected to an FR 80 from III which can plot directly onto cine-film. Running on this system at the SRC laboratories in Oxfordshire was the software animation package, Frolic, developed by C.Emmett.
My program was written in Fortran with calls to Frolic subroutines."
The whole project was 14 pages of #Fortran code.
