Squiggly wall art formed by summing three rotating vectors. 

Four ‘preset’ STLs are included. You can edit the parameters or randomise them in the OpenSCAD customiser (which has details of how to do so).

To access the presets in OpenSCAD, rename "SquigglyWallArt.json.txt" to "SquigglyWallArt.json" and put it in the same directory.

Default lines are 1.2 mm wide and 2 mm high.
