A cybersigilism butterfly tattoo design in black line, set inside a broken circle of spiked thorns. A mirrored butterfly with thorn-veined wings and curled antennae sits on a vertical axis, with a spiked ring behind it, on plain off-white. Swap in your own creature or symbol or change the ink colour.

A cyber sigilism tattoo design for the lower back, drawn as black ink linework on a plain flat off-white ground. The centrepiece is one butterfly seen from above, perfectly mirror-symmetrical on a single vertical centre line. It sits inside a thin spiky halo ring. Butterfly: a slender pointed body with a tiny head and two long curved antennae that end in hooked barbs. Two large upper wings sweep up and out as sharp blade shapes. Two smaller lower wings sweep down and out into long tapering tails. Every wing edge is a needle-thin outline, with no solid fills. Thin veins branch inside each wing like circuitry and thorns. Small curved rose-thorn barbs grow along the outlines. Every line swells slightly in its middle and tapers to a needle point at both ends. Some wing tips split into double points. A few long, elegant curved spikes sweep outward from the wing corners. Keep the spaces between lines open and generous, so the thin strokes stay separate and do not merge when tattooed. Halo: a thin circular ring around the butterfly with a slightly doubled hairline. Short sharp thorns radiate outward from it at even intervals, and a few longer mirrored spikes rise from the top and sweep from the bottom. The ring is broken in places so the wing tips and spikes can pass through. The thorns never cross the butterfly's body or fill its wing cells. All lines are crisp, pure black and uniform in tone. Add no shading, grey wash, glow, chrome, 3D effect, drop shadow or texture. Add no text, letters, numbers, stars or other symbols. Composition: the emblem is centred and fills about 70% of the square. There is a wide clear margin on all sides and a perfectly flat, clean ground, ready for an artist to trace into a stencil.
