US flag entirely out of metal by ggfergu –
Camera: Canon 5D MkIII with Tokina 11-16mm lens (the only APS-C lens I know of that will still work on frame). 4-stop ND filter to lengthen exposure. This was a 4 second exposure with yellow sparks from a steel grinder on scrap metal and steel wool in a kitchen whisk spun in a hand drill behind the flag, and white sparks from titanium (from the right). I manually popped the flag with a handheld strobe set to 1/4 power a couple times during the exposure (you can see a couple white rectangles hovering in the air above/left of the flag.
