Any Celestial Mechanics Modeling Sites?

Are there any calculators that allow you to model various situations in
orbital mechanics?

Maybe you input the weights, locations and velocities of various
planets, probes, dust clouds, etc., and then hit the run button and get
a neat looking video.

I may not be searching in the right places.

This would just be a fun thing, something for the non mechanics lay
person to play with.

There are a fair number of Java sites that do solar system scale stuff
and a lovely galaxy collider that gives pleasing renditions.

My links are out of date Google should get it.
