Here's the flower I created with Tiled Clones from that video, another zoomed in wallpaper.
Select Original (Shift/D) and pull out the original petal used for cloning, then fiddle with different colors. Radial gradient on petal, which doesn't look that great zoomed out, but I liked it when zoomed in. Those little dots in the center are fill pattern (Fill/Stroke Menu) on a circle object. Another gold circle behind it as the dots are transparent background. Exported and finished in Paint Shop Pro.
