'''Overview:'''

A simulation showing the superposition of two oscillations. 

Both oscillations and the sum are shown as a function of time. 

You may:
* Change each component's frequency
* Run in "slow motion" mode



'''Suggestions:'''  

Change the frequencies and analyse the resulting oscillation.

You can also play with close or disparate values for the frequencies.
