I've tried using the Shape Tool with Curve and Smooth join set.
I set two initial point, then a third 90 degrees and half the length.
The fourth 90 degrees again and half the length of the third.
Repeat until bored.
You then have to adjust the curve slightly between the first and second points and the last two.
You can vary the ratio of adjacent lines.
You can throw in a Mould Envelope to get a perspective.
