My approach creates a random line for each one.
Create an oval 12x6px.Select this and Create a Scatter brush.
Give it a name.
Draw a line and Edit Brush.
Change about eevry parameter there is:
Spacing (to overlap): ~50%; Randomis ~90-110%.
Offset: Alternating - Distance:~5% - Random: ~0-3%.
Scaling Random: ~75-132%.
Fill: All brush colours - Random Saturation: 0-~8% - Random Hue: 0-~10%.
Drawn lines, existing shapes with Line widths, straight or angled lines all dynamically change when adjusted for width and control points.
You can retweak a partcular line with a Re-edit without save.
You can Break Points with Line (not Shapes) and your can Reverse Paths.
I believe Scatter Brushes are the only Xara component that handles random.
Some examples:
The top Acorn is there to emphasise the positioning of the lozenges.
