Fragments of the fractal -like the tip of it

http://klein.math.okstate.edu/kleinian/src/

In this site you find a Fortran program with zillions of Kleinian fractals. Somebody is able to compile/understand that stuff? shocked smiley cheesy

It must be plenty of incredible things grin

i tried to compile it but it's complaining about some errors in the source code, i don't have enough time right now to understand what's happening.
I'll try again later smiley

i tried again but with ifort (Intel fortran compiler) instead of f77 (GNU Fortran compiler).
Much better but i still have a few errors :

One problem patched :

Quote
changed psgraph.F(53) to : call idate(iarray(1),iarray(2),iarray(3))

more problem patched :
changer all
Quote
ir=max(ir,0.5d0*unitpx)
to
Quote
ir=max(ir,INT(0.5d0*unitpx))
