2.  Add a slider "turn" over the real numbers ranging from 0.1 to 45.0.
3.  Add a slider "tilt" over the real numbers ranging from 0.1 to 45.0.

4.  Create a domain from -turn to turn.
5.  Create a domain from tilt-1 to tilt+1.
6.  Create a slider "steps" over the integers ranging from 2 to 50.

7.  Generate random numbers (Sets > Sequence > Random) with a range based on "turn" and a number set to "steps".
8.  Generate random numbers with a range based on "tilt" and a number set to "steps".
9.  Generate a random number with a range set to "0 To 360" (leave the number at 1).

10. Add a Python node.
    Give it four inputs: `move`, `first_turn`, `turns`, and `tilts`.
    Right-click on each of `turns` and `tilts` and set them to "List Access".

11. Add a slider "radius" over the real numbers
 ranging from 0.100 to 5.000.
12. Make a Pipe (Surface > Freeform) with the curve coming from the Python node's `a` output, the radius coming from the slider, and the caps set to Round (right-click the E input to set that).

13. Add a slider "first seed" over the integers ranging from 0 to 100.
14. Add a slider "iterations" over the integers ranging from 2 to 100.
15. Add a Series (Sets > Sequence) starting at "first seed", stepping by 1, for "iterations" numbers.

Now you should have a funky bowl that is randomly generated based on the seed settings you use!
It won't look much like a bowl when your iterations slider is below 10 (and even then it's a stretch), but by that point your computer will have a hard time keeping up with you if you're fine-tuning your parameters.
For me, at least, the bottleneck was actually the Pipe node, so you might want to use a Trigger node or right-click and disable it while you're playing with your sliders.
