I will try to write new context for interacting with tkinter thanks for
advice!
I need it because placing many charts and control panels in many
different windows is really not convenient
I have played with colorsliders demo, hmm... Tk sliders are easier to
use ( I had to learn how to select balls without zooming the whole
scene ) and I am not convinced to mix animation and controls.
Is it possible to highlight sliders while mouse is over? - such
interaction causes that one knows exactly what is happening with the
mouse.

And what about Glut?
