Hi Andrey

I was thinking about the Animations feature for Smath and in the pathway to reach it I guess that of big help would be to have the possibility to put in the body of a for/while loop a graph instruction ( my illusion is that this is possible already now with a very triky approach that probably is hidden into the system somewhere ).
This way to give the feeling of the animations effect we can do something like what I have imagined herewith:

this is not in Smath programming style ..but is just to give an idea of the approach suggested.
It is not the best , but is enough to start .
Apparently looks easy, but probably ( due to my ignorance of something outside Excel VBA environment ) it is very difficult to achieve.

It would be necessary to develop even a littel bit of functions for waiting a defined amount of time ( can be done in a nasty way looping on istructions used only with the only aim of wasting CPU time ..but is not very elegant )

Best regards and keep on with the good work.
