Can you assist me figure out this expression?

The first part,

wiggle(0,0)[0]

doesn’t really do anything, it just gives you the existing x coordinate, the same as

value[0]

the second part

wiggle(1,2)[1]

gives you the current y position plus a small wiggle in the y direction.

It would be the same as this

[value[0],wiggle(1,2)[1]]

or this

x = value[0];
y = wiggle(1,2)[1];
[x,y]
