[Q5.1.1]: To explore this idea of variation, play the following three videos several times - and write down how each one differs from the others.

The three videos were very similar, weren't they?  They followed the same general pattern, but two particular features of the performance varied in each of the videos.  If you didn't see them, play the videos again, watching very closely to what SlackerProm does.

[Q5.1.2]:  Which two features of the performance are varying?

You hopefully have noticed that what SlackerProm says changes - it's Aiie in the first two and then Yowza! in the third; and the number of turns he does before retreating is different in each one - just a couple in the first, then five turns in the second and 15 in the third.

Notice again how all three animations follow a set pattern, but that we have chosen some particular characteristics to be variable - what SlackerProm says and how many times he spins.

Let's explore further how this kind of variation can be set up...
