Looping wiggle() - Dan Ebberts's

Sometimes though, it would be extremely useful to be able to get the wiggle motion to loop. Here we'll take a look at a way to accomplish this by using a bit of clever math and taking advantage of one of wiggle()'s seldom used parameters.

Without question, wiggle() is an extremely handy and versatile tool for adding an element of randomness to a project.
freq = 1;
amp = 110;
loopTime = 3;
t = time % loopTime;
wiggle1 = wiggle(freq, amp, 1, 0.5, t);
wiggle2 = wiggle(freq, amp, 1, 0.5, t - loopTime);
linear(t, 0,  loopTime, wiggle1, wiggle2)
