1.) Create a GRID in Top View (x-y-view). Stay in Edit-Mode with all vertices selected (yellow))
2.) In x-z-view place the 3d-cursor above the middle of the grid.
3.) Press Shift-W and warp the Grid 360 degrees. You get some kind of tube. Stay in edit-mode.
4.) In the y-z-view press shift-w again and warp once more 360 degrees. This is easier if you extremely zoom in, so you get smaller number changes by mouse movement.

UPDATE: I tried it once more. At step 4 it is enough to warp 180 degrees.
You have to insert a mesh-key. At frame 1 create the grid. While still in edit-mode, press I and then mesh. Go to another frame (i.e. 100). Modify the grid and in edit-mode press I - mesh again.
I’m not sure if all vertices must be selected before inserting the key. But you must be in edit mode.
I got 360 degrees at step 4 first time i tried it.
Now i’m doing it againfor the animation - i can’t get that…
When i go into FULL zoon - and move the cursor one increment up - the first step is about 480 and the lower one is -280ish … so i can’t get to 360/180 - any ideas ?
I may just see if i can get a multiple of it up in the millions somewhere
Hmm, funny. I had these high values before zooming in. If I zoom up, so that I see only about 10 vertices, with CTRL pressed I get steps of five. Maybe you should scale up your initial grid? I scaled mine by factor 10.
