Algodoo

Quote: "switch on the plot of the higher pendulum and watch."

Response: Many users don't have a clue how to enable a plot, and how to properly configure it for the desired action. It's best to provide a button in the scene which automatically enables the plot, OR simply enable the plot before you upload the scene and leave it enabled.

Quote: "select the higher pendulum and rotate it by 0.1 degrees"

Response: Same situation as above. It's always better to provide buttons or other controls instead of expecting users to do things they don't know how to do.

Also, disable those annoying Algodoo clouds! They serve no purpose for a technical scene like this one and they are a distraction.

These are just suggestions, and you would need to know Thyme scripting in order to add buttons or other controls.

Oh, one more thing.... You named this scene Chaos Theory but it says nothing about the actual theory. Instead, it demonstrates a simple example of a chaotic system. Maybe rename it "Chaos example" or something similar.
